error on mathlab, and I have no idea how to correct it, please help me out :( Hello guys, I was using a class assignment using matlab, and the code is provided by the professor. All we need to do is use plug the function in and run it. But for some reason, I got this error: ??? Error using ==> mpower Inputs must be a scalar and a square matrix. Error in ==> @(x)(e^(cos(x))+8*x^2-3-x-4)^(1/5) Error in ==> fpi at 5 x(i+1)=g(x(i)); I dont see a problem in that, can someone point it out for me?
