How to plot an integral a function handle
显示 更早的评论
I want to plot an integral function, if 'y' is an arbitrary vector ,
N=51;
I=@(x)norm(exp(-1i*pi*x)- y'.*exp(-1i*pi*x*(0:(N-1)))).^2;
F=integral(I,-1,1,'ArrayValued',true);
plot(F);
This what I've tried, but it's not working.

I am not certain what you want.
Try this:
N = 51;
I = @(x,y) norm(exp(-1i*pi*x)- y'.*exp(-1i*pi*x*(0:(N-1)))).^2;
F = @(y) integral(@(x) I(x,y), -1, 1,'ArrayValued',true);
y = 1:10;
Fy = arrayfun(F, y);
figure(1)
plot(y, Fy)
