Simplify Symbolic Expressions - MATLAB & Simulink
www.mathworks.com › help › symbolic
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.

Expand only algebraic expressions, specified as the comma-separated pair consisting of 'ArithmeticOnly' and true or false. If the value is true, the function expands the arithmetic part of an expression without expanding trigonometric, hyperbolic, logarithmic, and special functions. This option does not prevent the expansion of powers and roots.

Defining Symbolic Expressions We can define symbolic functions using the sym command and syms command. Here is an example of creating a symbolic function for (a*X^2) + (b*x) + c: >> syms a b c x % define symbolic math variables >> f = sym('a*x^2 + b*x + c'); From now on we can use the f symbol to represent the given function.
