how to use malloc() to create a multidimension array

I want to dynamicly create a multidimensional array of a struct by using heap memory function malloc(). How can I do it?

Thanks.

The advice on www.eskimo.com is excellent. But a word of caution is in order: In a static array
double a[NROWS][NCOLS];
"a" is a pointer to the first element. In
"self-made" dynamic arrays this is
not the case. A subroutine taking a
static 2D-array as an argument may
not work with dynamic arrays.
