I have x and y data and im trying to fit to an integral equation and obtain the parameters x(1), x(2), and x(3)
This is the fitting equation
(1-(6*x(1))/(pi*sqrt(x(2))))*int(((((x(3)*cos(x(3))-sin(x(3)))^2)*exp(-1*fittingx))/((x(3)^2)*((sin(x(3)))^2)+x(2)*((x(1)/x(2))*(x(3)*cos(x(3))-sin(x(3)))+sin(x(3)))^2))
The integral is from 0 to infinity d(x(3))
Thanks!
