On a fresh 6179 installed on virgin machine, the Matlab "mw..."
does not appear in the "fx menu". As I opened some Fourier stuff
calling for this library => dead ! Couldn't find it from the plugin.

By coincidence, I opened my Bessel JY.sm,,, In that work sheet there is

solve(mwbesselj(1,x),x,0,18)

At this point, Smath manager offered to install the 8 MB Matlab, it did,
then solving the above demand !!!
Now, the Matlab "mw..." is installed in the "fx menu" and the dependent
Fourier stuff works ... A great tip, maybe for more collabs.

I do not often rebuild plugins. If the plugin does not work in the current version of the program, you need to try to remove it and install again. If this does not work, you can ask to rebuild the plugin for the current version of the program.

I rebuild Matlab plugin for 6179.
