ind2sub

Syntax

[i,j]=ind2sub(dim, ind)

[s1,s2,...,sn]=ind2sub(dim, ind)

Inputs

dim

Matrix dimensions.

Type: double | integer

Dimension: scalar | string | vector | matrix

ind

Linear index.

Type: double | integer

Dimension: scalar

Outputs

i,j

2-dimensional indices.

s1,s2,...,sn

N-dimensional indices.

Examples

Simple ind2sub example:

[i,j]=ind2sub([4,5], 7)

i = 3
j = 2

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

mat3D = randn(2,5,3);
	  [i,j,k]=ind2sub(size(mat3D), 10)

i = 2
j = 5
k = 1
