I have to determine the value of 2 unknowns a and b through nonlinear regression and predict the value of the equation y for x=2.6
the equation is y=((a+sqrt(x)./(b.*sqrt(x))).^2). i looked through my class pdf's and i found nothing related to non linear regression and searched on youtube found nothing helpful . Any clues please ? or links to helpful locations websites or mathworks that might contain info . I don't know where to search anymore .
