Of course, silly me for not realizing this.

Okay. I see that 'trapz' can handle matrix arguments:

X = [0:0.1:pi; 0:0.1:pi];
Y = sin(X);
trapz(X, Y, 2)
ans =

   1.9975
   1.9975

So, if 'm:mx' has the same length for all 'i' you should be able to 
vectorize this. If not, then I don't think you can do (at least not 
without rewritting 'trapz').

Lucky you ;-)
