The discussion revolves around solving a nonlinear equations system using MATLAB's fsolve function. The user encounters an error indicating that the maximum number of function evaluations has been reached when attempting to solve the equations. The suggested solution is to increase the MaxFunEvals option in the fsolve settings, as the current number of evaluations is insufficient for convergence. Users are encouraged to check the fsolve documentation for guidance on adjusting this parameter to resolve the issue.

Hi to everyone.I were to solve a nonlinear equations system consisting of two unknown parameters and two equations.I have written a Matlab m-file to define the functions in order to solve them by embeded fsolve Matlab command.But I end up with an error occurring on the command window, when i attempt to solve the equations by typing
>> x0=[0.0157;0.01585];
>> [x, functionvalue, control, feature]=fsolve('saumrd',x0);
where saumrd is the name of the m-file in which I defined the functions.The error occurred after typing the above script on command window is as follows:

Maximum number of function evaluations reached:
increase options.MaxFunEvals.

Is ther anyone who will comment on the error and guide me to overcome this proplem?Thanking you so much.

Look at your documentation, you're not converging to an answer within the number of maximum iterations allowed by fsolve. Look in the fsolve.m file and increase options.MaxFunEvals.
