eye
identity matrix
Calling Sequence
X = eye(m,n) X = eye(A) X = eye()
Arguments
- A,X
matrices, hypermatrices, or
syslin
lists- m,n
integer values: numbers of rows and columns for
X
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
. In case A
is an hypermatrix,
X
will be defined as
X(i,i,...,i) = 1
for all i
from 1 to min(size(A))
.
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.
