mwArray GetA(int num_indices, const int* index)

Return single element at the specified 1-based index. The index is passed as an array of 1-based indices.

C++ syntax

• #include "mclcppclass.h"
  double data[4] = {1.0, 2.0, 3.0, 4.0};
  int index[2] = {1, 1};
  double x;
  mwArray a(2, 2, mxDOUBLE_CLASS);
  a.SetData(data, 4);
  x = a.GetA(1, index);        // x = 1.0
  x = a.GetA(2, index);        // x = 1.0
  index[0] = 2;
  index[1] = 2;
  x = a.Get(2, index);         // x = 4.0
  

Arguments

num_indices.   Size of index array.

index.   Array of at least size num_indices containing the indices.

Return value

An mwArray containing the value at the specified index.

Description

Use this method to fetch a single element at a specified index. The index is passed by first passing the number of indices, followed by an array 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 sub-script 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.
