Extracting only certain data from a matrix
显示 更早的评论
I have a very large matrix and I need only certain data to show from it. I need only the data that has values of 3 in the first column. How do I find this.

Where M is your matrix:
X = M(:,1)==3;
B = M(X,:)

Hi,
You can try using this:
M(M(:, 1) == 3)
Hope this helps!

I think this needs to be
M(M(:, 1) == 3,:)
