Internal optimization function
LBSPR_NLLgtg(starts, LMids, LBins, LDat, gtgLinfs, MKMat, MK, Linf, ngtg, recP, usePen)
| starts | a vector of starting parameters, relative SL50 (SL50/Linf), deltaSL (SL95-SL50)/Linf, and F/M (in log space) |
|---|---|
| LMids | a vector of the midpoints of the length classes |
| LBins | a vector of length classes |
| LDat | a vector of lenght frequencies. Must be same length as LMids |
| gtgLinfs | a vector of Linfs for the growth-type-groups |
| MKMat | a matrix of M/K for each GTG and length-class |
| MK | the M/K value |
| Linf | the Linf value for the population as a hole |
| ngtg | the number of growth-type-groups |
| recP | a vector of recruitment by GTG |
| usePen | logical to use penalty for extreme estimates of selectivity |
