[MINC-users] [avsurf error]: Function '+' not defined for variables of class 'int32'

[Najmeh Khalili M.]

Hi Jon & Jim; thanks for responding.

In fact the matlab problem was because the matlab's int32
function worked only with matlab7 (and not matlab6.1 which I
was using).

HT to Pierre Bellec!

Cheers
Naj
