sparsifyc error

[mrtarkhan]

Undefined function or variable 'sparsifyc'.

Error in ncut (line 41)
W = sparsifyc(W,dataNcut.valeurMin);

is it compatible with Matlab 2015b?

I know that the question is old but I had this problem today so here the explanations

You need to recompile the file in 64 bits with the command

mex sparsifyc.gcc

Note that gcc needs to be in version 6.3.x so you probably need to install it

sudo apt install gcc-6 g++-6

On Windows you can install MinGW 6.3

Then chose the gcc-6 version when using mex

mex -v /usr/bin/gcc-6

Replace /usr/bin by the path to the application but on Linux it should be this on default
