Does anyone know how can I have a 2D-contour plot of some given data points?

I have the coordinates inside two vectors x and y. The problem is there is no analyctical function relating the height z, to the coordinates.

I have a seperate vector which has the values of z corrospondig to each (x,y) pair.

I would appreciate if you could help me with this.

Thanks in advance!

You might find the griddata function useful. It takes random (x,y) values and interpolates gridded z-matrices from them that contour and contourf can use.

You were right. I tried with reshape and it worked. Now I will interpolate to generate more data in the contour.

Thanks!
