nump = (1:10) .* (1:10).'; % Auto-Expand >= Matlab R2016b
For older Matlab versions:
nump = bsxfun(@times, (1:10), (1:10).');
denp from KL's solution is perfect already. This is 2 microseconds(!) faster on my computer, but less nice:
denp = zeros(100, 3);
denp(:, 1) = 1;
denp(:, 2) = repmat((1:10)', 10, 1);

nump = cell2mat(arrayfun(@(x) x:x:x*10,1:10,'uni',0))';
denp = [ones(100,1) repmat((1:10)',10,1), zeros(100,1)];
