spzeros

sparse zero matrix

Calling Sequence

sp=spzeros(nrows,ncols)
sp=spzeros(A)

Arguments

:nrows integer (number of rows) : :ncols integer (number os columns) : :A sparse matrix : :sp sparse zero matrix :

Description

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).

Examples

`sum`_(spzeros(1000,1000))
