spzeros(1)                     Scilab Function                     spzeros(1)
NAME
  spzeros -  sparse zero matrix

SYNTAX
  sp=spzeros(nrows,ncols)

  sp=spzeros(A)

PARAMETERS

  nrows   : integer (number of rows)

  ncols   : integer (number os columns)

  A       : sparse matrix

  sp      : sparse zero matrix

DESCRIPTION
  sp=spzeros(nrows,ncols,fill) 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).

EXAMPLE
  sum(spzeros(1000,1000))

SEE ALSO
  sparse, full, eye, speye, spones
