Am writing this topic to state a solution to a common MATLAB error that may appears to you if you are using it for your research and study. The problem happens when using SVMtrain for classification , here is the error log :
??? Error using ==> svmtrain at 470 Unable to solve the optimization problem: Maximum number of iterations exceeded; increase options.MaxIter. To continue solving the problem with the current solution as the starting point, set x0 = x before calling quadprog.
The solution to this problem is to increase the number of iteration of support vector machine train function .
