Compatibility Considerations
If you require the old behavior, replace instances of nextpow2 with
nextpow2(length(v)).
Math Libraries Not Available to Build MEX-Files with Compaq Visual
Fortran
MATLAB no longer provides the libdflapack.dll and libdfblas.dll math libraries
for building Fortran MEX-files with a Compaq
®
Visual Fortran compiler.
Compatibility Considerations
If you distribute MEX-files that call BLAS or LAPACK functions built on a Compaq
Visual Fortran compiler, you must also distribute the libdflapack.dll and
libdfblas.dll library files.
If MATLAB displays errors when loading a MEX-file and the Dependency Walker
indicates missing libdflapack.dll and/or libdfblas.dll libraries, contact the
MEX-file vendor for copies of the libraries. The third-party product, Dependency Walker,
is available from the Web site http://www.dependencywalker.com/.
