speye
sparse identity matrix
Syntax
Isp=speye(nrows,ncols) Isp=speye(A)
Arguments
- nrows
integer (number of rows)
- ncols
integer (number os columns)
- A
sparse matrix
- sp
sparse identity matrix
Description
Isp=speye(nrows,ncols)
returns a sparse identity
matrix Isp
with nrows
rows,
ncols
columns. (Non square identity matrix have a
maximal number of ones along the main diagonal).
Isp=speye(A)
returns a sparse identity matrix
with same dimensions as A
. If
[m,n]=size(A)
, speye(m,n)
and
speye(A)
are equivalent. In particular
speye(3)
is not equivalent to
speye(3,3)
.
