mxCreateStructMatrix (MATLAB Application Program Interface)

Create an unpopulated two-dimensional structure mxArray

C Syntax

#include "matrix.h"
mxArray *mxCreateStructMatrix(int m, int n, int nfields, 
         const char **field_names);

Arguments

m
The desired number of rows. This must be a positive integer.

n
The desired number of columns. This must be a positive integer.

nfields
The desired number of fields in each element.

field_names
The desired list of field names.

Returns

A pointer to the created structure mxArray, if successful; otherwise, returns NULL. The most likely cause of failure is insufficient heap space to hold the returned mxArray.

Description

mxCreateStructMatrix and mxCreateStructArray are almost identical. The only difference is that mxCreateStructMatrix can only create two-dimensional mxArrays, while mxCreateStructArray can create mxArrays having two or more dimensions.

Example
