Function Reference
— Function File: ind = sub2ind (dims, i, j)
— Function File: ind = sub2ind (dims, s1, s2, ..., sN)

Convert subscripts into a linear index.

The following example shows how to convert the two-dimensional index (2,3) of a 3-by-3 matrix to a linear index. The matrix is linearly indexed moving from one column to next, filling up all rows in each column.

          linear_index = sub2ind ([3, 3], 2, 3)
           8
