I have got the matrix of 729x6 elements. Each of the 729 elements are having 6 characters (i,j,k,l,m,n).

Also, I have certain initial conditions regarding these characters given and I want to delete the elements whose characters in the elements are not satisfying the initial conditions.

What coding, commands are required to carry out the task of applying initial conditions to the matrix of elements obtained in MATLAB?

The initial conditions include

i=0,1,2
k=1
l=1
m=1

Kindly tell. Thank you

I have attached the matrix of elements for ready reference.

mask = ismember(ijklmn(:,1), [0, 1, 2]) & all(ijklmn(:,3:5) == 1, 2);
ijklmn = ijklmn(mask, :);

So the code I had posted is working for you?

yes

But I am not getting expected outputs. I think it's might be I am taking wrong inputs for the same. I have to work upon the assumed inputs again and then try coding :(
