Hi,

I need to fit a complex function to some data points Couuld you please show me what Maple operations to use?

The function is:

pn := unapply(KT*bn*(sum((dWn[i](lambda)*(sum(c[i+r]*binomial(i+r, i)*(Lmbd0(lambda)/bn)^r, r = 0 .. nterm-i))+IWn[i](lambda)*(2*lambda^3-2)*(sum(r*c[i+r]*binomial(i+r, i)*(Lmbd0(lambda)/bn)^(r-1), r = 1 .. nterm-i))/(bn*(3*lambda^2)))/bn^i, i = 0 .. nterm)), lambda);

- 'IWn' and 'dWn' are known (and long) functions of lambda.
