# eye (Matlab function)

Identity matrix

### Matlab/Scilab equivalent

 Matlab Scilab `eye` `eye`

### Particular cases

Note that in Matlab, A can contain complex values (in these cases, only real part of A is taken in account), what Scilab function do not tolerate.

B=eye(A)

If A is a scalar, then Matlab returns a A*A identity matrix but in Scilab you get a 1, use eye(A,A) to get the same matrix B. If A is a vector, Scilab and Matlab give the same B. Finally, if A is a matrix, in Scilab, B will be a matrix having the same size as A whereas in Matlab, you get an error message.

### Examples

 Matlab Scilab ```B = eye(2) B = [1,0;0,1] B = eye(2,2) B = [1,0;0,1] B = eye([3,3]) B = [1,0,0;0,1,0;0,0,1]``` ```B = eye(2) B = 1 B = eye(2,2) B = [1,0;0,1] B = eye([3,3]) B = [1,0]```
