sinc

sinc関数

呼び出し手順

t=sinc(x)

引数

x

実数または複素数のベクトルまたは行列

t

実数または複素数のベクトルまたは行列

説明

xがベクトルまたは行列の場合, t=sinc(x)はベクトルまたは行列となります. ただし, x(i)~=0の場合にt(i)=sin(x(i))/x(i), x(i)==0の場合にt(i)=1 です.

x=linspace(-10,10,3000);
plot2d(x,sinc(x))
[X,Y] = meshgrid(-10:0.25:10,-10:0.25:10);
f = sinc(sqrt((X).^2+(Y).^2));
mesh(X,Y,f);

  • cos — 余弦関数
