extract a slice from a 2D matrix with specific values

Hi,

I want to extract a slice of a 2D matrix from a bigger 2D matrix with certain values. So, if I have a matrix as follwoing:

M = [1 2;
    1 4;
    7 1
    9 1
    0 3
    0 4
    9 0
    8 0];

And I want to extract a slice that only has values in the second column equal one.

Any help would be appreicted.

Thanks.

M = [1 2;
    1 4;
    7 1
    9 1
    0 3
    0 4
    9 0
    8 0];
y = M(M(:,2)==1, :)

y = 2×2

7 1 9 1
