I'm writing a function to fit a curve.

Here is what I wrote:
temp1=A/w*sqrt(4*ln(2)/PI);
if (x{temp2=exp(-4*ln(2)*(x-xc)^2)*(abs(t-(x-xc))^p1);
y=temp1*integrate(temp2)}
else
{temp2=exp(-4*ln(2)*(x-xc)^2)*(abs(t-(x-xc))^p2);
y=temp1*integrate(temp2)}

Origin kept on giving me an error message saying that there are too many bad functional evaluations and that parameters may be out of range. Anyone have any idea what is wrong?

Your equation does not have a valid condition for the if clause:
if (x{temp2=exp(-4*ln(2)*(x-xc)^2)*(abs(t-(x-xc))^p1);

It's not clear what your intent was for this conditional.

I may help, but show me your equation as in text book.
A brief description will be great unless
it is private research.
Preferabbly reply to my e.mail because I hate
crumbling in the forum.
