By convention the dimension is always rows first and columns second, in the spirit of R1C1 reference style, and the ordering of row and column arguments in functions such as INDEX and OFFSET.Įxcel uses during selection resizing operations ( m and n are common to MatLab). The size of an array is described by the number of rows and number of columns. The expressions 'scalar', 'row vector' and 'column vector' are common to the MatLab (matrix laboratory) application software.įig 1: Column, Row and MultiDimensional array - CollArr (6R x 1C), RowArr (1R x 4C), and MDArr (4R x 3C) 12 elements

Multi dimensional array - range B11:D14 shaded grey.

Row array (row vector) - range B9:E9 shaded blue.Column array (column vector) - range B2:B7 shaded green.In Excel the concept is best illustrated by example, see figure 1 (worksheet: WS arrays) where 'a group of items' means a contiguous range, In particular, an array can be a: An array's orientation is classified by its dimension (such as column orientation, or row orientation, discussed further in section 1).

matrix based linear algebra array operationsĪn array can be described as a group of items that can be acted on either individually or collectively.mathematical element wise array operations, and.Excel structures able to hold data, most commonly, the array of cells on a worksheet (by reference, name or constant).This material about arrays and vectors involves three concepts:
