Hi MathworKS community,
i hava a set of data that i can plot like the picture below , as you see it dosen't cover all the area
so when i use interp2 to find the value of Z inside the contour i get this error 'Input grid is not a valid MESHGRID.'
i have an idea : fill the empty area with Nan, but it's a little bit confusig for me.
any solution?
contourf(X,Y,Z)colormap jet;interp2(X,Y,Z,3000,50) %for example i want to interpolate at X=3000 and Y=50
