Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have a quick question regarding MatLab.

I have 3 matracies A, B and C.

For every entry equal to 1 in B, I want to let the corresponding entry in A be an integral of x from 0 to C.

ex.

for all (i,j)

if B(i,j)==1 then let A(i,j)=quad(@(x) x, 0, C(i,j))

A quick way to do this for large matracies I thought was to use the following syntax:

A(B==1) = quad(@(x) x, 0, C(B==1))

But get the following error:

??? Error using ==> quad at 70

The limits of integration must be scalars.

Is there any way around this other than a "for i, for j" statement?

Thanks,
