How do i view the velocity profile

I have this code which has reshaped column vectors into matrices, i now want to find the velocity profile for x,y,u,v how do i do this please?

A = importdata(filename,delimiterIn,headerlinesIn);

%%Matrices%%%%
xi = 214; yj = 134;

x= zeros(yj,xi); 

y= zeros(yj,xi);

u= zeros(yj,xi);

v= zeros(yj,xi);

%%Matrix population

for j=1:yj
    x(j,:) = A.data((j-1)*xi+1:j*xi,1);

      y(j,:) = A.data((j-1)*xi+1:j*xi,2);

      u(j,:) = A.data((j-1)*xi+1:j*xi,3);

      v(j,:) = A.data((j-1)*xi+1:j*xi,4);
  end

Read about quiver

quiver(x,y,u,v) ;

yeah, I tried it but it gives a vector plot, I wanted the velocity profile

You mean a color plot? Any example picture?
