Lets say we have the following fitting function:.Code:void fit(float x, float y, int ndata, float sig, int mwt, float *a, float *b, float *siga, float *sigb, float *chi2, float *q,float *r2)
Then we haveSo basically it is saying . Why is this?Code:for (i=1;i<=ndata;i++) *chi2 += SQR(y[i]-(*a)-(*b)*x[i]); *r2 +=
Is there any easy way to obtain from so that I can use it in the program? Note that we have .
