[Gridflow-dev] cv.Div, cv.Mul + errors

[Alexandre Castonguay]

Salut Mathieu,

I tried [cv.Div] and [cv.Mul] but somehow they return empty values [0,0,0].

Here is the test of the error function, at least sending grids of different 
dimensions does not crash pd  : 

error: ArgumentError: OpenCV error: status=-209 func_name=cvAdd err_msg="" 
file_name=cxarithm.cpp line=843
optional/opencv.c.fcs:141:in `int erreur_handleur(int, const char*, const 
char*, const char*, int, void*)'
/home/alx/Documents/src/pd-0.40-2/extra/GridFlow/base/main.rb:142:in 
`method_missing'

Merci!

Alexandre
