plAlloc2dGrid
( | f, |
| nx, | |
ny); |
Allocates the memory for a matrix of type PLFLT_MATRIX (organized as an Iliffe column
vector of pointers to row vectors). As a result the matrix
can be accessed using C/C++ syntax like *f[i][j]. The
memory associated with this matrix must be freed by calling
plFree2dGrid once it is no longer required.
f
(PLFLT_NC_MATRIX *If the allocation is a success, a pointer to a matrix
(organized as an Iliffe column
vector of pointers to row vectors) is returned. If the
allocation is a failure, then the returned value of
f will be NULL.
nx, ny
(PLINTDimensions of matrix to be allocated.
This function is used in our C (and C++) examples 8, 9, 11, 14, 16, 20, 21, 22, 28, 30.
