Using the C++ Math Library

Overview

A one-dimensional subscript contains a single index, which can be a scalar, a vector, a matrix, or a call to the colon() function. The size and shape of the one-dimensional index determine the size and shape of the result. For example, a one-dimensional column vector index produces a one-dimensional column vector result.

To apply a one-dimensional subscript to an N-dimensional array, you need to know how to go from the one-dimensional index value to a location inside the array. See Array Storage for complete details on how MATLAB counts one-dimensionally through arrays of N dimensions.

Note    The range for a one-dimensional index depends on the size of the array. For a given array A, it ranges from 1, the first element of the array, to prod(size(A)), the last element in an N-dimensional array. Contrast this range with the two ranges for a two-dimensional index where the row value varies from 1 to M, and the column value from 1 to N.
