| Function | get pointer to a matrix element |
|
| Syntax C/C++ | #include <MFstd.h>
float * MF_Pelement( fMatrix MA, ui ht, ui len, unsigned m, unsigned n ); |
| C++ MatObj | #include <OptiVec.h>
T * matrix<T>::Pelement( const unsigned m, const unsigned n ); |
| Pascal/Delphi | uses MFstd;
function MF_Pelement( MA:fMatrix; ht, len, m, n:UIntSize ): PSingle; |
|
| CUDA function C/C++ | #include <cudaMFstd.h>
float * cudaMF_Pelement( fMatrix MA, ui ht, ui len, unsigned m, unsigned n );
|
| CUDA function Pascal/Delphi | uses MFstd;
function cudaMF_Pelement( d_MA:fMatrix; ht, len, m, n:UIntSize ): PSingle;

|
| Description | A pointer to the element MAm,n is returned.
It is possible to use this function for write access to a matrix element through the dereferenced-pointer syntax: |
| C/C++ | *MF_Pelement( MA, ht, len, m, n ) = 3.5; |
| Pascal/Delphi | MF_Pelement( MA, ht, len, m, n )^ := 3.5;
This sort of write access is not possible for the CUDA version of this function.
As a safer way of writing single elements, use MF_setElement.
Read-only access to matrix elements is provided by the related functions, MF_element and MF_getElement. |

| Return value | pointer to the matrix element MAm,n |
