Using the C++ Math Library

Using One-Dimensional Subscripts

This section describes how to select:

• A single element with a one-dimensional scalar index
• A vector with a one-dimensional vector index
• A subarray with a one-dimensional matrix index
• All elements in a matrix with a colon index

All examples work with example matrix A. Notice that the value of each element in A is equal to that element's position in the column-major enumeration order. For example, the third element of A is the number 3 and the ninth element of A is the number 9.

A = 
1 4 7
2 5 8
3 6 9
