This is asked daily for many years now. See:

- https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval
The answer is always the same: Don't do this. Create an array instead and use the numbers as indices. This is faster, nicer, more flexible, easier to debug, to maintain, to expand and to read.
V = zeros(1, n); % For scalars
m = 7;
M = zeros(m, n); % For column vectors
C = cell(1, n); % For variables with different sizes
for k = 1:n
V(k) = k ^ 2;
M(:, k) = rand(m, 1);
C{k} = sprintf('%g', k);
end
