Y = eye(n)
Y = eye(m,n)
eye([m
n])
Y = eye(size(A))
eye(m, n, classname)
eye([m,n],classname)
Y = eye(n) returns the n-by-n identity matrix.
Y = eye(m,n) or eye([m n]) returns an m-by-n matrix with 1's on the diagonal and 0's elsewhere.
Note The size inputs m and n should be nonnegative integers. Negative integers are treated as 0. |
Y = eye(size(A)) returns an identity matrix the same size as A.
eye(m, n, classname) or eye([m,n],classname) is an m-by-n matrix with 1's of class classname on the diagonal and zeros of class classname elsewhere. classname is a string specifying the data type of the output. classname can have the following values: 'double', 'single', 'int8', 'uint8', 'int16', 'uint16', 'int32', 'uint32', 'int64', or 'uint64'.
x = eye(2,3,'int8');
The identity matrix is not defined for higher-dimensional arrays. The assignment y = eye([2,3,4]) results in an error.
