spzeros

疎ゼロ行列

呼び出し手順

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

パラメータ

nrows

整数 (行数)

ncols

整数 (列数)

A

疎行列

sp

疎ゼロ行列

説明

sp=spzeros(nrows,ncols)は, nrows 行, ncols 列の 疎ゼロ行列を返します. (sparse([],[],[nrow,ncols])と等価です)

sp=spzeros(A) は, Aと同じ次元を有する疎ゼロ行列を返します. [m,n]=size(A)の場合, spzeros(m,n) および spzeros(A) は等価です. なお, spzeros(3)spzeros(3,3)と等しくなりません.

sum(spzeros(1000,1000))
