How to vectorize histogram of rows in a matrix?

Is there any way to vectorize the following where it doesn't use the for loop?

rows = 5;
cols = 20;
z = randn(rows, cols);
for i = 1:size(z,1)
    figure;
    histogram(z(i,:))
    title(['Histogram of row ',num2str(i)]);
    xlabel('Bins');
    ylabel('Frequency');
end

This is probably the fastest way. Any other method will likely make it slower and more complicated.
