# ind2subn

Below is a demonstration of the features of the ind2subn function

## Contents

```clear; close all; clc;
```

## Syntax

[A] = ind2subn(siz,ind);

## Description

This function is similar to MATLAB's ind2sub function. However the output is collected in an array that is numel(ind) x numel(siz). This function constructs an array where the columns represent the subscripts indices for the input linear indices (ind).

## Examples

2D indices

```ind=[1 2 6 12]
siz=[6 6]
[IJ] = ind2subn(siz,ind)
```
```ind =

1     2     6    12

siz =

6     6

IJ =

1     1
2     1
6     1
6     2

```

3D indices

```ind=[1 2 6 12 666]
siz=[11 11 11]
[IJK] = ind2subn(siz,ind)
```
```ind =

1     2     6    12   666

siz =

11    11    11

IJK =

1     1     1
2     1     1
6     1     1
1     2     1
6     6     6

```

4D indices

```ind=[1 2 6 12 666 6666]
siz=[11 11 11 11]
[IJKL] = ind2subn(siz,ind)
```
```ind =

1           2           6          12         666        6666

siz =

11    11    11    11

IJKL =

1     1     1     1
2     1     1     1
6     1     1     1
1     2     1     1
6     6     6     1
11     1     1     6

```
