I want to find values of the variables v1,v2 and v3 at which function value is maximum.
F = Em.*exp(1i*ifft(fftshift(sqrt(v1)*Emmf11a+sqrt(v2)*Emmf11b.*exp(-1i*(v3*pi)))
where v1,v2 and v3 are variable for the function and Em, Emmf11a and Emmf11b are in matrix form values and complex.
for example
Em = [1+2i 2;4-1i -12+4i]
Emmf11a = [1+2i 2;4-1i -12+4i]
Emmf11b = [1+2i 2;4-1i -12+4i]

I would recommend using fminsearch() or patternsearch().
