mwArray operator()(mwIndex i1, mwIndex i2,

mwIndex i3, ..., )

Purpose Return single element at specified 1-based index

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 o f 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 passe d as a comma-separated list of 1-based indices.

This operator is overloaded to support 1 through 3 2 indices. T he

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 o ffset is returned, accessing data in column-wise order, or

NumberOfDimensions() (mul tiple subscript indexing), in which cas e,

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.
