I have really find it difficult to plot both flow and direction of flow vectors superimposed each other. I have plotted the direction of the flow vector using
But the magnitude is given by
Is there a way to plot magnitude of vector with direction
Thanks in advance.

Really, I think you can solve your problem by reading the documentation for quiver() more carefully.
The first two arguments specify the spot where each vector will begin. The next two specify the length of each component.
x_start = 1; y_start = 2; x_length = 7; y_length = 3;
figure scale=0; quiver(x_start,y_start,x_length,y_length,scale); % Set scale==0, to prevent auto-scaling. See documentation.
For your real plot, x_start etc are going to be column vectors with your actual data.
