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]
