New Multithreading Capability in MATLAB Functions
The MATLAB functions for Fourier transforms fft, fft2, and fftn, and their inverses ifft,
ifft2, and ifftn are now multithreaded. In addition, the MATLAB functions prod, sum,
max, and min are multithreaded.
64-bit Support in LAPACK and BLAS
MATLAB supports 64-bit integers for matrix dimensions in LAPACK, and BLAS. Linear
algebra operations can now handle matrices of dimensions greater than
2 1
31

.
Compatibility Considerations
MEX files that call BLAS or LAPACK need to be updated. All integer variables passed
into BLAS or LAPACK need to be of type mwSignedIndex. MEX files compiled in
previous versions of MATLAB that call BLAS or LAPACK could lead to undefined
behaviors. If you have existing code that generates MEX files that pass variables to BLAS
or LAPACK you need to update the code to use the proper data types and recompile.
Upgrade to ACML 4.1.0
AMD Core Math Library (ACML) is upgraded to version 4.1.0.
