cumprod
累積積
呼び出し手順
y=cumprod(x) y=cumprod(x,'r') or y=cumprod(x,1) y=cumprod(x,'c') or y=cumprod(x,2) y=cumprod(x,'m')
パラメータ
- x
- ベクトルまたは行列 (実数または複素数) 
- y
- ベクトルまたは行列 (実数または複素数) 
説明
y=cumprod(x)は,
	xがベクトルまたは行列の場合,
	xの全てのエントリの列方向の
	累積積をyに返します.
y=cumprod(x,'c') (または, 等価的に,
    y=cumprod(x,2)) は
	xの列の
	要素毎の累積積をyに返します:
    y(i,:)=cumprod(x(i,:))
y=cumprod(x,'r') (または, 等価的に,
    y=cumprod(x,2)) は
	xの行の
	要素毎の累積積をyに返します:
    y(:,i)=cumprod(x(:,i)).
y=cumprod(x,'m') は
	xの最初の1より大きい次元方向の
	累積積となります(Matlabとの互換性用).
