The Simplify Symbolic Expression task enables you to interactively simplify or rearrange symbolic expressions. The task automatically generates MATLAB ® code for your live script. For more information about Live Editor tasks, see Add Interactive Tasks to a Live Script.

This MATLAB function performs algebraic simplification of expr. 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.. For instance, this workflow gives better results …

Jan 20, 2011 · 2 CommentsShowHide1 older comment. As you have used symbolic function, to get output displayed in decimal format use "vpa" command. This comes out of the 'subs' command when 'syms' is associated. The simple way to have a simplified solution is, use vpa (x,d) command where x gets simplified upto d digits.

Upon substituting into a symbolic expression I get very long analytic expressions for numbers, e.g. (2^(1/2)*(3^(1/2)*pi*(5^(1/2)/4 - 1/4)*(1/120000 + ...

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 Symbolic Rational Expressions Simplify two rational expressions by using simplifyFraction . syms x y fraction = (x^2-1)/(x+1); simplifyFraction(fraction)

Another approach that can improve simplification of an expression or function is the syntax simplify(f,'Steps',n) , where n is a positive integer that controls ...
