How do I simplify the numerical portion of my symbolic expression using Symbolic Math Toolbox 3.2 (R2007a)?. Follow. 112 views (last 30 days).

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.

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 …

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.

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. Using this task, you can:

Apr 30, 2014 · Simplifying numbers in symbolic function. 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 + i/6000000)t + .... is there any way to simplify these numbers down to a single double precision complex number in the symbolic expression to make ...
