Replace NaN with corresponding elements in another array.

I can find the locations of all the NaNs in an array, but how can I replace those elements with the corresponding elements of another array.

A = original array with NaNs in it
B = array with desired replacement values
x = isnan(A);
A(x) = B(x);

How can I replace the zeros in the resulting array with the corresponding elements in A?

[James Tursa]

The zeros in what resulting array? If you have an array C the same size as A and you want to replace the zeros in C with the corresponding values from A, then use a similar technique as above. E.g.,

x = (C == 0);
C(x) = A(x);
