| mxCreateStructMatrix (C and Fortran) | |||||||||||||||||||||
| Purpose CSyntax | |||||||||||||||||||||
| Create unpopulated 2-D structure mxArray #include "matrix.h" mxArray *mxCreateStructMatrix(mwSize m, mwSize n, int nfields, const char **fieldnames); mwPointer mxCreateStructMatrix(m, n, nfields, fieldnames) mwSize m, n integer*4 nfields character*(*) fieldnames(nfields) | |||||||||||||||||||||
| Fortran Syntax | |||||||||||||||||||||
| Arguments | |||||||||||||||||||||
| m | |||||||||||||||||||||
| The desired number of rows. This must be a positive integer. | |||||||||||||||||||||
| n | |||||||||||||||||||||
| The desired number ofcolumns. This must be a positive integer. nfields The desired number of fields in each element. fieldnames The desired list of field names. | |||||||||||||||||||||
| Each structure field name must begin with a letter and is case sensitive. The rest of the name may contain letters, numerals, and underscore characters. Use the namelengthmax function to determine the maximum length of a field name. Returns A pointer to the created structure mxArray if successful, and NULL in C (0 in Fortran) otherwise. The most likely cause of failure is insufficient heapspacetoholdthereturnedmxArray. Description mxCreateStructMatrix and mxCreateStructArray are almost identical. The only difference is that mxCreateStructMatrix can create only two-dimensional mxArrays,whilemxCreateStructArray can create mxArrays having two or more dimensions. | |||||||||||||||||||||
