But my problem is that, I don't know how can I give a number to variable and get the result as a number. For example the answer of my code is answer=exp (-10*a); download call of duty pc gratis
Create Symbolic Matrix Variables - MATLAB & Simulink
WebJul 2, 2024 · There are several ways to do this. Starting with symfun: syms x f = symfun (x.^2, x); xv = linspace (-10,10,100); f1 = double (f (xv)); This is equivalent to: syms x % or: syms f (x) f (x) = x.^2; xv = linspace (-10,10,100); f1 = double (f (xv)); Alternative is using the subs approach as suggested by Adam.

WebTo create symbolic expressions, first create symbolic variables, and then use operations on them. For example, use syms x; x + 1 instead of sym ('x + 1'), exp (sym (pi)) instead of sym ('exp (pi)'), and syms f (var1,...,varN) instead of f (var1,...,varN) = sym ('f (var1,...,varN)'). … Certain functions, such as solve and symReadSSCVariables, can return a … This MATLAB function performs algebraic simplification of expr.
