Contour plot with 3 vectors and x, y vectors on a logarithmic scale

Hello,

I've got 3 vectors

x =[10^(-10) 10^(-9) 10^(-8) 10^(-7) 10^(-6) 10^(-5) 10^(-4) 10^(-3) 10^(-2)]

y =[10^(-10) 10^(-9) 10^(-8) 10^(-7) 10^(-6) 10^(-5) 10^(-4) 10^(-3) 10^(-2)]

and z which is the error that takes values from 5 to 0.01.

I need to create a contour plot. However, I cannot use meshgrid, as the step on my x and y axis should be very small and Matlab crashes when I'm trying that.

Any ideas about resolving it?

Many thanks

What error message is it that you get? Or does MATLAB itself crash? Or does it just "hang" ?
