To evaluate a symbolic object for a particular value of a variable, The symbol name matches the symbol's value it's easier to use the equivalent " syms x". in future x will be treated as a symbol entity). The command x=sym('x') creates a symbolic object called x which has the corresponding string representation x (i.e. To convert a symbolic object into a number use double - e.g. The following, for example, produces the result 5/6. Only digits, arithmetic operations will be different to those in
Objects are essentially strings, but even if those strings contain Familiarity with them will help when using maple. Things of this type are created using the sym and With the Symbolic Math Toolbox comes a new matlab datatype - symbolic Numerical answers, so adding the 2 lines below will print out '4' and '3'. By using matlab'sĮval command you can make seven be evaluated, getting the The answers are right, but not in a very useful form. You'll find that a and b are given in terms of the symbol So for example, if you try something similar to the Note that maple doesn't automatically know the values of variables you've You can quote the expression as a string (see the first example above), orĭefine x to be a symbol as in the following Matlab's unhappy that x doesn't have a value. Matlab will say " ? Undefined function or variable 'x'" because People have is with how Matlab and Maple interact. Matlab's own routine, which does prime factorisation). (note that if you try to use factor directly, you'll call YouĬan send maple commands to it using matlab's mapleĬommand, or for common routines like int (to integrate)įirst, some examples to convince you that it's worth reading on! Is actually a cut-down version of the Maple program. Integrating, differentiating, etc) and also has some solving routines. Which performs symbolic maths commands (factorising, simplifying, Useful that we have installed is called the Symbolic Toolbox Matlab has lots of adds-ons (called toolboxes).

See Matlab - the Symbolic Toolbox based on Mupad for Only any use with matlab releases prior to 2008b. Refers to the Symbolic Toolbox based on Maple rather than Mupad, so it's Learning to use the Symbolic Toolbox might save you hours of time.

You can share your symbolic work with other MATLAB users as live scripts or convert them to HTML, Word, LaTex, or PDF documents. Your computations can be performed either analytically or using variable-precision arithmetic, with the results displayed in mathematical typeset. You can perform dimensional computations and convert between units. Symbolic Math Toolbox lets you analytically perform differentiation, integration, simplification, transforms, and equation solving. The toolbox provides functions in common mathematical areas such as calculus, linear algebra, algebraic and differential equations, equation simplification, and equation manipulation.
In the MATLAB ® Live Editor, you can get next-step suggestions for symbolic workflows. You can create, run, and share symbolic math code. Symbolic Math Toolbox™ provides functions for solving, plotting, and manipulating symbolic math equations.
