Isp = speye(A) Isp = speye(nrows, ncols)
integer (number of rows)
integer (number os columns)
sparse matrix
sparse identity matrix
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(A)
is equal to
speye(m,n)
.
![]() | Hence, speye(3) is equal to speye(1,1) , NOT
to speye(3,3) . |
