I am asking if there are off-the-shelf curve-fitting algorithms,maybe for octave, that will allow constraints on some of the parameters,or is custom programming the only way to go. AK
If the constraints are linear, then a general solution is possible. In fact there is a free version available for Matlab (although I don't know what sort of license is involved).
If the constraints are non-linear (as in your example) then the difficulty of a solution will depend upon whether or not the variables are pure real or complex valued.
