Unfortunately that thing is not a function gnuplot can readily handle for you. In a nutshell, you first need something you can plot as a function, before it can be fitted to data.
You would need either of the following
a closed-form solution of that integral, expressible in terms of the built-in functions and operators
an external DLL fitting gnuplot's "import" command, which provides a numerical evalution
to allow this
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
i want to fit the below attched equation anf find out Y,L
constants are mentioned in the image,
Y is the varriable function and i want ot and fitt the above equation and find out the values of Y,L
