Dear members;
I have matrix of B*C dimensions.
and I have to write a program that verify if the final bits are '0' or '1'. If final bits are '0', the program change them to '1'.

[s1, s2] = size(A);
d = gcd(s1, s2);
n1 = s1 / d;
n2 = s2 / d;
vCol = n2:n2:s2;
for iCol = 1:numel(vCol)
iRow = (iCol - 1) * n1 + 1;
A(iRow:iRow + n1 - 1, vCol(iCol)) = 1;
end
Alternative - more Matlab'ish without loops:
sizeA = size(A);
n = sizeA ./ gcd(sizeA(1), sizeA(2));
idx = sub2ind(sizeA, 1:sizeA(1), repelem(n2:n2:s2, n1));
A(idx) = 1;

When someone help us, we appreciate its help using (Sir) to show our respect and greatful for him. But if other persons don't use this expression, it doesn't mean it's impolite. Sometimes saying "Thank you so much" is sufficent.

Thanks for the explanation. It is not trivial to communicate with persons from different cultural regions.
