mxSetProperty (C and Fortran)
Set value of public property of MATLAB object
#include "matrix.h" void mxSetProperty(mxArray *pa, mwIndex index, const char *propname, const mxArray *value);
subroutine mxSetProperty(pa, index, propname, value) mwPointer pa, value mwIndex index character*(*) propname
Pointer to an mxArray which is an object.
Index of the desired element of the object array.
In C, the first element of an mxArray has an index of 0. The index of the last element is N-1, where N is the number of elements in the array. In Fortran, the first element of an mxArray has an index of 1. The index of the last element is N, where N is the number of elements in the array.
Name of the property whose value you are assigning.
Pointer to the mxArray you are assigning.
Use mxSetProperty to assign a value to the specified property. In pseudo-C terminology, mxSetProperty performs the assignment:
pa[index].propname = value;
Property propname must be an existing, public property and index must be within the bounds of the mxArray. Use mxGetNumberOfElements or mxGetM and mxGetN to test the index value.
mxSetProperty makes a copy of the value before assigning it as the new property value. This might be a concern if the property uses a large amount of memory. There must be sufficient memory (in the heap) to hold the copy of the value.
