Thank you Cem Bonfil sir for your valuable reply. I am able to create .f3d file (Complex Data 3D File Format) using the procedure which are explained in OptiBPM_User_Reference.pdf. So if you kindly describe the scripting process (I saw VBscripting manual,but sir I didnot understand ). I want to convert
input= exp(-((r.^2)./W.^2)) (gaussian beam)
input= bessel j (0,kr.*r)).*exp(-((r.^2)./W.^2)) (bessel beam)
These above equations into .f3d file format. Sir kindly describe how can I convert MATLAB file into .f3d file.
