Just give the matrix as the first argument of NIntegrate.
Here's an example:
NIntegrate[{{x, x^2, x^3}, {x^4, x^5, x^6}, {x^7, x^8, x^9}}, {x, 0, 1}]
evaluates to
{{0.5, 0.333333, 0.25}, {0.2, 0.166667, 0.142857}, {0.125, 0.111111,0.1}}
Cheers,
Dave Snead

I have a 3X3 matrix of functions fij[x], for i,j = 1,2,3, and I want to
NIntegrate all nine elements over 0<x<1 to get a matrix of constants. Is
there an easy way to do this other that doing 9 individual NIntegration's?
