2D Matrix calculation

Hi there,

Fairly new to neuron.

If A is a 1000x1 vector containing non-integer values,

B is a 1000x1 vector also containing non-integer values,

and x is a vector containing integers from 1-36

How would I best go about calculating the following 1000x36 matrix,C:

 C(A,B,x) = A/x + B/x

Fyi A and B are changing in time, and values of x are points in space (along an x-axis). So im wanting to see how the values at each point in space are changing over time, with 1000 time samples.

So maybe it should be written like this instead:

 C(t,x) = A(t)/x + B(t)/x

Many thanks

I would use bsxfun.

These produce the same result:

C1 = bsxfun(@mrdivide, A, x) + bsxfun(@mrdivide, B, x);
C2 = bsxfun(@rdivide, A, x) + bsxfun(@rdivide, B, x);
