If you mean by in-lined intrinsics, this is worth while only for certain cases (4x4 for float data type), which you could find documented. More generally, you would look at MKL library which comes with Intel C++.

You can use /QxSSE2 or /arch:SSE2 to compile, use /Qvec-report3 to report if the loop is vectorized with SSE intruction.

Didn't you get enough hits when you typed "SSE transpose" in the search box?
