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.

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 …

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.

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.

Apr 18, 2017 · Answers (2) I get a==NaN and b==pi/2 - asin (M). So they are not the same. I find that applying simplify to a does not change it significantly. I randomly substituted M=2, l=3. With those two values, the two expressions are not equal. One of the two goes complex from about gama = pi to gama = 17*pi/16 . From 17*pi/16 to roughly 48*Pi/41 the ...
