Ive been struggling several weeks with inputting a user defined function for a nonlinear fitting. My function is Y=integrate{p3*(p1/2)/[(p2-x)^2-(p1/2)^2]*(cos p2)^4}*dp2, the constrain of the integration is from x -/2, to x+/2. X is the independant var., and y is the dependant var., p1, p2, p3 are the three parameters.
if anyone knew how to input this functioin into origin for a nonlinear fitting, please help me out! Great thanks!! |
