I have a surface of which i would like to compute a section with the z = a plane using contourc function.
if we try to plot the surface:
surf(pinionSurf.X, pinionSurf.Y, pinionSurf.Z)
we can notice this surface is not built from meshed [X,Y] grid.
if i use the contour function i have no problems getting the contourMatrix:
a = 3;
contourMat = contour(pinionSurf.X, pinionSurf.Y, pinionSurf.Z, [a, a]);
But for performance reasons, and since i need just the matrix without the plotting, i would like to use the contourc function to perform the "low-level" computation.
The problem is contourc function accepts only x and y array values which are going to be meshed into a grid internally (the helper indeed says x and y length have to be respectively the same size as the rows and columns of Z matrix).
My question is: is there a way to manipulate my data in order to use it inside contourc function and have the same results the normal contour function gives?
I attached my surface example into a struct.
