spzeros — sparse zero matrix
sp=spzeros(nrows,ncols) sp=spzeros(A)
integer (number of rows)
integer (number os columns)
sparse matrix
sparse zero matrix
sp=spzeros(nrows,ncols)
returns a sparse zero matrix sp
with nrows
rows, ncols
columns.
(Equivalent to sparse([],[],[nrow,ncols])
)
sp=spzeros(A)
returns a sparse zero matrix with same
dimensions as A
. If [m,n]=size(A)
, spzeros(m,n)
and
spzeros(A)
are equivalent. In particular spzeros(3)
is not
equivalent to spzeros(3,3)
.
