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).
