WebApr 5, 2016 · Anyway, implementations like the one in fsolve will have problems with too small gradients or step lengths. A better idea might be to apply a least-squares solver, i.e., minimize the sum of squares of the components of F. Function pracma::lsqnonlin will do this, squaring and summing the components of F automatically. ... WebIt generates an optical field at double the frequency of the original laser beam, with the result that part of the incoming laser power will be converted to half the original wavelength (second-harmonic generation (SHG) or frequency doubling) (Figure 9). Since energy has to be conserved, any gain in the SHG beam is traded for a decrease in ...

You could let the code do this a given number of times until it doesn't receive the warning, or it has tried too often. The starting point for the optimisation is given by x0. You can read the full documentation here.
