Hello;
I want to contour velocity field . This velocity field has one column for X , one column for Y and one column for velocity values. How can I contour this matrix?
The Matrix is written such as following:
X [ m ] Y [ m ] Velocity v.Gradient

Hello Mohammad,
if I understand your question correctly, it doesn't make much sense to draw a contour plot for your data, since the y component is always the same. You can't get more info out of this data then a simple plot could show you
If 'D' is your matrix, just do
plot(D(:,1),D(:,3),'*')
best,
Stephan

I think it would be better if you describe your problem in a general form instead of posting a huge file or matrix. Important would be, e.g., if you know the (x,y) data points or get velocity samples at random locations?
