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?
