The interface between Matlab and “Maple” is smooth and it is easy to move in and out of this Symbolic Math Toolbox. For convenience only in this guide we will refer to the smaller Symbolic Math Toolbox attached to Matlab as “Maple”.

The tools in the Symbolic Math Toolbox are built upon the core of the powerful software program called Maple® which is used in many universities in Australia and overseas. You will be solving and computing with mathematical symbols rather than numbers. Each expression can be given a variable name (also symbolic) thereby allowing algebraic, trigonometric and other functional manipulations and simplifications as well as permitting differential and integral calculus. However, commands in the Symbolic Math Toolbox enable you to enter formulae such as sin(2*x), x*exp(x), x^2+3*atan(x), cos(x)^2+sin(x)^2, etc, where x is a symbolic variable. For example if you merely enter the single command sin(x) after the prompt you receive the error message A variable x must have a numerical value (or array values) before expressions involving x can then be evaluated.

Advances in Computational Mathematics, 45(1), 137-152. Verified computation of the matrix exponential. Most functions like exp ⁡ ( x ), and related matrix functions by contour integrals. Matrix functions are special functions made by matrices. One example of a matrix function occurs with the Algebraic Riccati equation, which is used to solve certain optimal control problems. In the case of a matrix function, the input and the output values are matrices. In mathematics, a function maps an input value to an output value.
