mxSetCell (External Interfaces/API Reference)

Set the value of one cell

C Syntax

#include "matrix.h"
void mxSetCell(mxArray *array_ptr, int index, mxArray *value);

Arguments
array_ptr
Pointer to a cell mxArray.

index

Index from the beginning of the mxArray. Specify the number of elements between the first cell of the mxArray and the cell you want to set. The easiest way to calculate index is to call mxCalcSingleSubscript.

value

The new value of the cell. You can put any kind of mxArray into a cell. In fact, you can even put another cell mxArray into a cell.

Description

Call mxSetCell to put the designated value into a particular cell of a cell mxArray. Use mxSetCell to assign new values to unpopulated cells or to overwrite the value of an existing cell.

If the specified cell is already occupied, then mxSetCell assigns the new value. However, the old cell value remains in memory until you call mxDestroyArray.

Note Inputs to a MEX-file are constant read-only mxArrays and should not be modified. Using mxSetCell* or mxSetField* to modify the cells or fields of an argument passed from MATLAB causes unpredictable results.
