Hello Matlab experts,
My questions is about using contourc function to get a isoline in a 2D contour. For example,
iso_line = contourc(x,y,function_of_x_y,[0.5 0.5]);
I assume that the algrithme is interploilating the function_of_x_y on meshgrids(x,y) to get the isoline at 0.5. My question is what is the interpolation function? is it a linear interpolation? Does the uniform or non-uniform grids affect the 2D iso_line matrix?
Thanks in advance.
Bin
