Subject: Contour Plots with Vectors

I've done quite a bit of reading over this topic and still can't quite get my code to work.

I have three 1 dimensional vectors. The  x and y values correspond to cordinates and the z values will be a magnitude reading taken at the x and y cordinates.

For example x=[1 4 2 3] y=[5 4 2 6] z=[1.1 1.9 1.6 1.2] 

I need to make a contour plot of this data. I know I need z to be at least a 2x2 matrix and so the data must be interpolated at the points I don't know. 

My question is if I know the values below how do I use interp2 to find the '+' values so I can use that resulting matrix in a contour plot

1.1  +     +    +
+    1.9   +    +
+    +    1.6   +
+    +    +   1.2

Thanks for any and all help
