How do I create a matrix from from the answers of each iteration of a for loop?

1 次查看(过去 30 天)
This is my for loop code,
N = 4
for yn = cos(pi*(0:N)/N)
yp = cos(pi*(0:N)/N);
bottom = 1./(yn - yp)
end
This is the output,
bottom =
Inf 3.4142 1.0000 0.5858 0.5000
bottom =
-3.4142 Inf 1.4142 0.7071 0.5858
bottom =
-1.0000 -1.4142 Inf 1.4142 1.0000
bottom =
-0.5858 -0.7071 -1.4142 Inf 3.4142
bottom =
-0.5000 -0.5858 -1.0000 -3.4142 Inf
How do I create a
[Inf 3.4142 1.0000 0.5858 0.5000
-3.4142 Inf 1.4142 0.7071 0.5858
-1.0000 -1.4142 Inf 1.4142 1.0000
-0.5858 -0.7071 -1.4142 Inf 3.4142
-0.5000 -0.5858 -1.0000 -3.4142 Inf] matrix from my output, because the last bottom iteration is the final answer?

N = 4;
yn = cos(pi * ( 0 : N ) / N);
yp = cos(pi * ( 0 : N ) / N);
yp = reshape(yp, 1, 1, []);
bottom = squeeze(1 ./ (yn - yp))
bottom = 5×5
Inf 3.4142 1.0000 0.5858 0.5000 -3.4142 Inf 1.4142 0.7071 0.5858 -1.0000 -1.4142 Inf 1.4142 1.0000 -0.5858 -0.7071 -1.4142 Inf 3.4142 -0.5000 -0.5858 -1.0000 -3.4142 Inf
