Access violation from MKL

[Chao_Z_1]

Hi, all:

I built up a project based on Armadillo(6.500.5) and MKL(11.x). The project was built as a mex file that can be called by MATLAB (2015a).

When the pinv/svd routine in Armadillo was called for the first time in MATLAB, it ran OK and produced right result. However, when I ran "clear functions" in MATLAB and re-built my project in MS Visual Studio 2013, then re-ran the mex file in MATLAB, access violation was reported from MKL:

Here if I turn off "MKL" in Visual Studio, and use lapack/blas library from CLAPACK, the whole program was OK.

Any idea on this problem?

Thanks!

You may probably try to use another version of MKL, as we had the problem with SVD in the past. The current version of MKL is 2020 and available for download.
