[Mex] How to compile file with Intel Intrinsics (SSE)?

I have a simple test.c file with Intel Intrinsics (SSE function calls). I can not compile using Mex within Matlab environment, but I can using gcc outside Matlab environment.

Outside Matlab, I use the following command: gcc test.c -o test -msse4

Inside Matlab, I try the following command: mex gcc test.c -o test -msse4 It fails with error "-msse4" is not a valid option.

If I try: mex gcc test.c -o test I get linking error, which is expected

How can I compile this file? Is it impossible?

Hello,

did you try "mex CC=gcc CFLAGS=-msse4 test.c"? I think it should work.
