zeros

ゼロからなる行列

呼び出し手順

y=zeros()

y=zeros(x)

y=zeros(m1,m2,..)

引数

x,y

行列

m1, m2,..

整数

説明

ゼロ行列を作成します (0*onesと等価).

zeros(m1,m2)

(m1,m2) 行列の場合.

zeros(m1,m2,..,mn)

ゼロで埋めた (m1,m2,..,mn) 行列を作成します.

zeros(A)

Aの同じ大きさの行列.

zeros(3)

a=3と指定したzeros(a) となり, すなわち, 3x3 行列とはなりません!

zeros()

単一のゼロを返します

repmat(0, sizes) can be used to generate an array of zeros with sizes=[m1 m2 ..] given as a vector.

xsyslin リスト (状態空間または伝達関数の線形システム)の場合でも, zeros(x) は有効で,ゼロ行列を返します.

zeros(3)
zeros(3,3)
zeros(2,3,2)

repmat(0, [2 4 2])
