WebAll code for generation must be MATLAB code. In particular, you cannot use a custom black-box function as an objective function for fsolve. You can use coder.ceval to evaluate a custom function coded in C or C++. However, the custom function must be called in a MATLAB function. fsolve does not support the problem argument for code generation. Webfsolve is a wrapper around MINPACK’s hybrd and hybrj algorithms. Examples. Find a solution to the system of equations: x0*cos(x1) = 4, x1*x0-x1 = 5.
