Get all the new features and functionality of Mathcad 13!

Building on more than 20 years of Mathcad technology, Mathcad 13 continues to be the standard for technical computing and engineering calculation documentation, and provides users with unsurpassed breadth and depth of application—enabling increased productivity and quality. The latest release—Mathcad 13—adds to the mathematical and ease-of-use feature set that has made Mathcad the tool of choice for hundreds of thousands of professional engineers and scientists. Mathcad 13 also adds expanded equation tracing, called provenance, to Calculation Management in large engineering organizations.

Calculation Management and Reporting


In this Mathcad 13 example, a series of explicit calculations (keywords and left-hand sides hidden) show substituted values followed by the final numerical result.

NEW! Explicit Calculation
Many certification organizations require reported calculations to show substituted values before results are computed. Mathcad 13 introduces a new symbolic keyword, explicit, to do these substitutions. Users can choose to substitute some, all, or none of the defined variables in an expression without reducing the expression numerically. Several of these statements in subsequent calculations can show a step-by-step trail of substitutions, followed by a final numerical evaluation. This functionality greatly improves the ability of a user, auditor, or organization to verify and validate calculations.

NEW! Expanded 2D Graph trace options
A host of new line and symbol options have been added to 2D graphs in Mathcad 13. Now users can communicate complex technical information more clearly in visual format. One of the most important new options is the ability to choose the plotted symbol frequency independently from the total number of points used to create smooth connecting lines.

The full Windows color palette, new filled symbols, and independent control of line and symbol weight round out the trace settings feature set. These many new options, available through an updated, modern Windows style settings dialog, provide precise control over graph appearance.

"The trace improvements help me automate and streamline program development for radar systems design, while getting to market faster in an extremely competitive industry." - Mathcad 13 beta participant

 

In Mathcad 13, temperature units allow users to express unit-checked results in common linear-transform scales.

NEW! Unit Functions: Temperature units, Decibels, and Other Custom Engineering Units
In Mathcad 13, units can have a functional form. The most important examples of this are the Fahrenheit and Celsius temperature scales. These new units can be used to define values, or to convert results in the unit placeholder, just like multiplicative units. Not only can you carry and balance functional units through calculations, you can display results in almost any conceivable scaling to suit documentation needs. It is possible to define your own unit functions, using them in expressions with standard unit notation.

User-specified default units
In Mathcad 13, a whole new interface enables the viewing of existing unit settings for base and derived units, and the creating of a custom unit system by adding, modifying, and deleting rules for unit simplification.

Metadata Enhancements
Mathcad 13 enhances traceability and auditability on equations by creating annotation fields on more types of math regions, including results and referenced files. Provenance information is also now automatically replicated when multiple regions are copied and pasted simultaneously.  

Program Debugging and Math Functionality

Mathcad 13 introduces several important new features for working with programs, parametric fitting, linear algebra, and other solvers.

NEW! Program Debugging
New Mathcad functions ‘trace’ and ‘pause’ enable users to report intermediate values in a program to a Trace Window, and optionally step or halt a program if it’s not producing the desired results. The ‘trace’ and ‘pause’ functions will output to the Trace Window when debug mode is specifically toggled on, so users can leave these functions in their programs but only use them when needed. Results from the Trace Window can be copied for reuse elsewhere.

The new trace function in Mathcad 13 lets users format and report intermediate program values in debug mode.
"The 'trace' and 'pause' statements are a major improvement for programming. I found these very helpful not only in debugging a program, but to check on the program flow and partial results."
- Mathcad 13 beta participant
 

Enhanced parametric fitting
Mathcad 13 adds a number of improvements and extensions to the genfit function. The new algorithm solves some types of model functions faster and more accurately than the old one. Further, the new algorithm will allow users to supply the fit function only, without generating symbolic derivatives for each fit parameter. This option saves time and complexity in setting up the function, and avoids bad fits resulting from incorrect derivatives. The function has also been extended to accept any combination of parameter names, rather than insisting that parameters be specified as elements of a vector. This allows users to specify the model function using discipline-correct notation.

Enhanced linear algebra
Mathcad 13 reduces the time required for all of the linear algebra functions, including matrix inversion, multiplication, linear system solution, and eigenvalue reduction.

"The linear and non-linear unit support, temperature in particular, will be extremely useful to our calculations where we evaluate steam and thermodynamic process conditions." - Mathcad 13 beta participant


 

As shown in Mathcad 13, long, complex calculations will show the specific quantities supplied and required in the arguments for any function call.


Enhanced Unit Error Messages
Mathcad 13 enhances error messages for cases in which the values supplied have the wrong units. The error messages pinpoint the type of error and suggest the correct type of unit so users can quickly correct their work. Unit-specific error messages decrease debugging time, showing the quantities a function expects for its arguments. Users can also look at function signatures in Mathcad 13 by evaluating the function name.


 
"Unit error checking is one of Mathcad's major advantages and forces users to adopt good habits. Improving the error checking will be a major benefit in much of my work." - Mathcad 13 beta participant

UI and Documentation Enhancements

NEW! Autosave
Mathcad users can now choose to Autosave their work at a user-specified time interval, helping to manage loss of work.

NEW! Compatibility Switches
Users can set which way they would like constructs to behave, according to version number, using the compatibility switches. The constructs that are switchable include array assignment of multiple variables, local assignment return value, 0/0, and the precision used for truncation functions.

New Additions to Mathcad Resources
Mathcad's online resources continue to provide hundreds of worksheets that illustrate the depth of Mathcad's mathematical power and the variety of applications that Mathcad supports. All of these worksheets are live, so as you read the Tutorials or QuickSheets you can watch Mathcad at work, change the inputs, and see the results in the outputs as they update. The Resources window automatically pops up the first time you start Mathcad. A new Programming Tutorial addresses more topics in Mathcad programming, and new QuickSheets show advanced solving methods.

NEW! Migration Guide
In addition to the traditional Help and Resources, Mathcad 13 documentation offers an important new resource for experienced users. The Migration Guide discusses math constructs that have been upgraded in recent versions and any incompatibilities those may create with older versions. The guide gives specific instructions on migrating documents efficiently to take advantage of new functionality and remove errors. It shows best practices to optimize documents, and suggests methods of working with the latest Mathcad technology.
