Hi all!
Now i have this formula:
min sum(|A*M1(n)*exp(j*theta*n)-M2(n)|^2) ,n =0,...,N-1;
Unknown parameters
A: complex value
theta:real value

Known data:
M1(n):samples
M2(n):samples

I want to make that formula minimum,how can i do?I only know that it's a nonlinear least squares problem.please help me,thank you!
