2D contour of X,Y,Z vectors

Hey all,

so i have X,Y vectors which their values are not positive integers and i have another vector z.

i created a matrix that maches between the values in Z to their coresponding X,Y coordinates.

i need to have a 2D contour plot as shown in the attached image -how can i do it?

thank you!

If you've made a matrix Z corresponding to the x and y-values (that seems to be well-behaved) this should work:

contour(x,y,z)

Look at the help for contour for more information. If you need to directly make a contour plot from vectors alos look at

tricontour
