I want to create a new matrix which is has the same values as my original matrix, M, minus those rows whose first column values are less than 3.
Does anyone know how I could correct my code to do this?
M=set7;
Mm=table2array(M);
N=Mm(Mm(:,1)>=3)
for (Mm(1:end,1)>=3)
B=Mm(:,2)
end
Nn=zeros(size(B,2))
Nn=(N,B);
Thanks!

If I'm understanding correctly, I believe your third line is enough (with the addition of a colon in the second subscript of M to avoid linear indexing):
idx = M(:,1) >= 3; % indices of rows to keep
N = M(idx,:);
