Expression Wrapping of Math Output in the MuPAD Notebook Interface

The new default format of presenting results enhances readability by wrapping long output expressions, including long numbers, fractions and matrices.

Symbolic Solver Handles More Non-Algebraic Equations

The enhanced rationalize function in MuPAD helps the symbolic solver to handle more systems of non-algebraic equations. In particular, this improvement enables the toolbox to solve more systems of trigonometric equations.

Improved Performance in the Ordinary Differential Equation Solver

The ordinary differential equation solver demonstrates better performance.

Improved Performance for Polynomial Arithmetic Operations

The MuPAD functions gcdex, partfrac, polylib::resultant, and solvelib::pdioe now demonstrate better performance.

New MuPAD polylib::subresultant Function Computes Subresultants of Polynomials

polylib::subresultant computes subresultants of two polynomials or polynomial expressions.

MuPAD partfrac Function Accepts the New List Option

With the new List option, partfrac returns a list consisting of the numerators and denominators of the partial fraction decomposition.

New MuPAD inverf and inverfc Functions Compute the Inverses of Error Functions

The inverf function computes the inverse of the error function.

The inverfc function computes the inverse of the complementary error function.

New MuPAD numlib::checkPrimalityCertificate Function Tests Primality Certificates

numlib::checkPrimalityCertificate tests primality certificates returned by numlib::proveprime. For information about proving primality of numbers, see "Proving Primality" in the MuPAD documentation.

New Demos

There are three new demos that show how to solve equations and compute derivatives and integrals:

• Solving Algebraic and Differential Equations

• Differentiation

• Integration

To run the new demos, enter symeqndemo, symdiffdemo, or symintdemo in the MATLAB Command Window.

Functionality Being Removed or Changed

Functionality	What Happens When You Use This Functionality?	Use This Instead	Compatibility Considerations

MuPAD prog::testcall	Errors	Nothing	No replacement
MuPAD prog::testerrors	Errors	Nothing	No replacement
Old syntax of MuPAD prog::getOptions	Errors	The new syntax	Update all instances of prog::getOptions calls using the new syntax.
Old syntax of MuPAD prog::trace	Errors	The new syntax	Update all instances of prog::trace calls using the new syntax.
