mwArray operator()(int i1, int i2, int i3, ..., ) :: C++ Utility Library Reference (MATLAB Compiler)

MATLAB Compiler

mwArray operator()(int i1, int i2, int i3, ..., )

Return single element at the specified 1-based index. The index is passed as a comma-separated list of 1-based indices. This operator is overloaded to support 1 through 32 indices.

C++ syntax

#include "mclcppclass.h"
double data[4] = {1.0, 2.0, 3.0, 4.0};
double x;
mwArray a(2, 2, mxDOUBLE_CLASS);
a.SetData(data, 4);
x = a(1,1);      // x = 1.0
x = a(1,2);      // x = 3.0
x = a(2,2);      // x = 4.0

Arguments

i1, i2, i3, ..., . Comma-separated list of input indices.

Return value

An mwArray containing the value at the specified index.

Description

Use this operator to fetch a single element at a specified index. The index is passed as a comma-separated list of 1-based indices. The valid number of indices that can be passed in is either 1 (single subscript indexing), in which case the element at the specified 1-based offset is returned, accessing data in column-wise order, or NumberOfDimensions() (multiple subscript indexing), in which case, the index list is used to access the specified element. The valid range for indices is 1 <= index <= NumberOfElements(), for single subscript indexing. For multiple subscript indexing, the ith index has the valid range: 1 <= index[i] <= GetDimensions().Get(1, i). An mwException is thrown if an invalid number of indices is passed in or if any index is out of bounds.
