Im trying to implement the argmax operator in matlab.

That means that i want the vector Θ that maximeze this expression. can be viewed as a real number that depends on Θ. I found the frobenius norm in matlab but i dont know how to find that Θ. I also tried fmincon and symbolic but without success.

fmincon should have been fine. Since you have no constraints, though, fminunc might be better. fminsearch might also be sufficient if p and K are small.
