# MATLAB: Solving a formula in Matlab

formula

Hello everyone,
In the following formula : X= 2y + 10 log(1+ E/S)
I want the user to input X, y, and S. Is there anyway i can get matlab to give me the value of E without having to rewrite the formula?
Thank you so much!

• x = input('Enter the value of x: '); % request user inputy = input('Enter the value of y: ');S = input('Enter the value of S: ');f = @(E) 2.*y + 10*log(1+ E./S) - x; % create an anonymous function[Eval, fval]= fsolve(f, 1); % solve your equation
or you can also:
syms Ef = 2.*y + 10*log(1+ E./S) == x;solve(f, E)
If log refers to the base of 10 rewrite f by replacing log with log10.
