You also can simplify symbolic functions by using simplify. syms f (x,y) f (x,y) = exp (x)*exp (y) f = simplify (f) f (x, y) = exp (x)*exp (y) f (x, y) = exp (x + y) Simplify Using Options By default, simplify uses strict simplification rules and ensures that simplified expressions are always mathematically equivalent to initial expressions.

simplify automatically chooses the unit to rewrite into. To choose a specific unit, use rewrite. Get Simpler Result by Expanding Expression In most cases, to simplify a symbolic expression using Symbolic Math Toolbox™, you only need to use the simplify function.

simplifyFraction Simplify symbolic rational expressions collapse all in page Syntax simplifyFraction (expr) simplifyFraction (expr,'Expand',true) Description example simplifyFraction (expr) simplifies the rational expression expr such that the numerator and denominator have no divisors in common. example

Simplify these symbolic expressions: syms x a b c S = simplify (sin (x)^2 + cos (x)^2) S = 1 S = simplify (exp (c*log (sqrt (a+b)))) S = a + b c / 2 Simplify Matrix Elements Call simplify for this symbolic matrix. When the input argument is a vector or matrix, simplify tries to find a simpler form of each element of the vector or matrix.

In most cases, to simplify a symbolic expression using Symbolic Math Toolbox™, you only need to use the simplify function. But for some large and complex expressions, you can obtain a faster and simpler result by using the expand function before applying simplify.

To add the Simplify Symbolic Expression task to a live script in the MATLAB Editor: On the Live Editor tab, select Task > Simplify Symbolic Expression. In a code block in your script, type a relevant keyword, such as simplify, symbolic, rewrite , expand, or combine. Select Simplify Symbolic Expression from the suggested command completions.

Simplify expressions involving exponents and logarithms. In the third expression, use log(sym(3)) instead of log(3).If you use log(3), then MATLAB ® calculates log(3) with the double precision, and then converts the result to a symbolic number.

Transform your expression into the particular form you require (expanded, factored, or expressed in particular terms) by choosing the appropriate function.
