Including legends for plots under the FOR LOOP

I would like to plot a figure with a for loop and want to include the legends for each single plot; any one with the help, here is the code

A = 100;

nr = length(t);

nc = length (K);

X = zeros ( nr , nc);

for i = 1 : nr for j = 1:nc

X (i,j) = A .* (1 - exp(- K (j) .* t (i)));

    end
end

for i = 1 : nc

    plot(X (:,i))

    hold on

end

Is it possible include the legend inside the for loop ?
