Fitting

[syang-6]

Can MathCad fit spectral curve with functions containing complex values? Do we need any package?

Hi Shu,

With Mathcad you can draw the module and the phase of a complex function  as functions of a real variable( ω). You can draw the imaginary part as a function of the real one to the varying a parameter. The fitting function requires a vector of real values, as in the  following function (interp):

Yes to your first question, no to your second.

Without more information, that's as complete an answer as I can give.
