Origin Version (Select Help-->About Origin): 7.5PRO
Operating System: WinXP
I'm using compiled c functions for fitting using the pfm and fitting is extremely slow. I can fit my spectra in a second or two using the built in gauss function. When i implement the same gauss function in c and try to fit, it takes about 2 minutes per iteration. It can't possibly be taking 2 minutes for the calculations can it? Is there a chance that there is a problem with origin passing data slowly to the external function?
Thanks!

I'm attempting to implement my functions in a DLL. I don't have any experience with DLL's unfortunately, so I'm attempting to use the example that comes with the PFM. It includes the DLL_Func.c source and DLL_Func.dll files. In theory I should be able to just compile the DLL_Func.c to get DLL_Func.dll but unfortunately I can't get Origin to compile it. The compiler can't find the windows.h header file, which I would imagine is a standard header that should be included. I tried compiling using the windows.h header from the Dev-C++ (Free C/C++) compiler, but the compiler just gives me a bunch of errors, so i'm guessing that header won't work. Any ideas where the correct windows.h might be? I believe I can modify the code in the example DLL for my function, but it's no good if it can't compile.
Thanks!

I have also found fitting OriginC functions in the PFM to be quite slow. As far as I'm aware, the only solution is to code the function(s) in an external DLL. |
