# eye¶

## Purpose¶

Creates an identity matrix.

## Format¶

y = eye(n)
Parameters: n (scalar) – size of identity matrix to be created. y (NxN identity matrix) – identity matrix, containing 1’s down the diagonal and 0’s everywhere else.

## Examples¶

x = eye(3);


The code above assigns x to be equal to:

1.0000 0.0000 0.0000
0.0000 1.0000 0.0000
0.0000 0.0000 1.0000
