在 Octave 中创建和绘制分段函数
Create and plot a piecewise function in Octave
所以我想绘制这个函数
为-1
首先我创建了分段函数
function x = pieceWise(t)
if t >= 0 & t <3
x = exp(-t);
else
x = 0;
endif
然后在这里调用并绘制它
x = linspace(-1,5,1000);
y = pieceWise(x);
plot(x,y)
但输出始终为 0
任何提示都会很有帮助。谢谢
你应该向量化你的代码:
1;
function x = pieceWise(t)
x = zeros (size (t));
ind = t >= 0 & t < 3;
x(ind) = exp(-t(ind));
endfunction
x = linspace (-1, 5, 1000);
y = pieceWise (x);
plot (x, y)
grid on
print out.p
