I would like to slove the nonlinear equation above and I use matlab to code below but the command window showed: Undefined function 'fsolve' for input arguments of type 'function_handle'.
How should I use the fsolve function or is there any other way to solve these nonlinear equation?
Thank you very much!
clc; clear;
f=@(x) [2.*x(1)-x(2)-exp(-x(1));-x(1)+2.*x(2)-exp(-x(2))];
fsolve(f,[-5,-5])

Hi,
In order to employ fsolve() function, you should have optimization toolbox installed in your computer.
fsolve is part of optimization toolbox and thus, you have gotten such an error message.
