DCOPY Fortran Subroutine

[Pablo_V_1]

Hello,

Does DCOPY have some lenght limit? In my fortran code I copy a 65000x2000 matrix using this subroutine, and I think that it is generating some problems in my results.

Thanks!

There is no Fortran intrinsic by that name nor do we supply it as a library routine. This must be a routine in your own source.

Sorry Steve.

I am talking about "?copy" routine that is included in Math Kernel Library. 

Thanks

Pablo: DCOPY is a BLAS routine that is provided in MKL, so asking in the MKL forum would have been more appropriate.

What are the declarations of the source and destination arrays that you call that subroutine with, and are you running 32-bit code or 64-bit code? What are the compiler options that you used, and what do you mean by "some problems"?
