on an evenly-spaced x-y meshgrid. What do the various colors represent in the contourf( ) plot? There's no labeling, like, say, a colormap would provide. My motivation to plot a function's level sets is to then overlay it with plots of convergent sequence...
Here is the Matlab result: Here is my result: Could someone explain the interpolation algorithm MATLAB uses internally? It seems to create sharp, defined edges, while my implementation leads to a smooth gradient. I'm interested in understanding what makes the ...

First, how many points determine a plane? THREE. That is, if you have a surface z(x,y), then EXACTLY 3 points are needed to determine a plane. And if you have 4 points, there will in general be no perfectly planar surface that passes through all...

yes. The number of elements created by meshgrid (or ndgrid) in the arrays wx and wy equals the number of grid points in two (or n) dimensions - and that's where the constraint is evaluated. 댓글을 달려면 로그인하십시오. ...
