eye
identity matrix
Calling Sequence
X=eye(m,n) X=eye(A) X=eye()
Arguments
- A,X
matrices or
syslin
lists- m,n
integers
Description
according to its arguments defines an
m
xn
matrix with 1 along the main
diagonal or an identity matrix of the same dimension as
A
.
Caution: eye(10)
is interpreted as
eye(A)
with A=10
i.e.
1
. (It is NOT a ten by ten identity matrix!).
If A
is a linear system represented by a
syslin
list, eye(A)
returns an
eye
matrix of appropriate dimension: (number of outputs
x number of inputs).
eye()
produces a identity matrix with undefined
dimensions. Dimensions will be defined when this identity matrix is added
to a matrix with fixed dimensions.
