M is a table where if a specific column in M is =1 the respective rows in the subsequent columns (starting at cl1 and ending at cl2) should be 1 as well. I tried something like this but it didn't work
X=table2array(M(:,cl1-1)); % where cl1 is the first column that i want to change its values
x0=find(X==1);
for i=1:length(x0)
for j=cl1:cl2 %cl2 is the last column that I want to change
M(x0(i),j)=1;
end
end
Any help is greatly appreciated

No loop should be needed.
X = M{:,cl1-1};
M{X == 1, cl1:cl2} = 1;
