plAlloc2dGrid: Allocate a block of memory for use as a 2-d grid of type PLFLT.

Allocates a block of memory for use as a 2-d grid of type PLFLT. The grid is a vectored 2-d C-style array and so can be accessed using syntax like *f[i][j]. The memory associated with the grid must be freed by calling plFree2dGrid once it is no longer required.

f (PLFLT ***, output) Pointer to a PLFLT grid. On success f will point to a pointer to the vectored 2-d array of type PLFLT. If the allocation fails f will be NULL. nx, ny (PLINT, input) Dimensions of grid to be allocated.

This function is currently available in C, C++, perl and tk.

This function is used in examples 8, 9, 11, 14, 16, 20, 21, 22, 28, 30.
