Hi
I have a problem with specifying constrants and initial values for
FindFit, when the parameters are defined as a table.
This is my model and the parameters (params)
model = a*(.5 + Sum[b[i]*Cos[2.00000*i*t*Pi/180], {i, 1, 500}]);
params = Join[{a}, Table[b[i], {i, 1, 500}]]
B[i_] = FindFit[data, model, params, t, MaxIterations -> 1000, AccuracyGoal
-> 4]
However I would like to constrain the b[i] parameters to be less than one.
Also if possible , that b[n+1]<=b[n]. What should the syntax be for this?
The number of parameters is too large to specify the constrains
individually.
Thanks,
VM
