sub2ind

Syntax

ind = sub2ind(dim,i,j)

ind = sub2ind(dim,s1,s2,...,sn)

Inputs

dim

Matrix dimensions.

Type: double | integer

Dimension: scalar | string | vector | matrix

i,j

2-dimensional indices.

Type: double | integer | char | string | logical | struct | cell

Dimension: scalar | string | vector | matrix

s1,s2,...,sn

N-dimensional indices.

Type: double | integer | char | string | logical | struct | cell

Dimension: matrix

Outputs

ind

Linear index.

Examples

Simple sub2ind example.

sub2ind([2,4;5,2],2,5)

ans = 10

sub2ind example with a 3-dimensional matrix of size 2x5x3

mat3D = randn(2,5,3);
	  sub2ind(size(mat3D),2,3,1)

ans = 6
