2013-09-06 06:25:50 +0100 | asked a question | 3-D Smooth Surface Plots I want to plot a smooth 3D surface plot using a matrix of integer numbers. Presently my 3d plot consist of 12X12 matrix but the plot output is jagged and less appealing. Therefore I would like to smoothen the plot using interpolation/extrapolation or cubic splines method or any other method so that I get a smooth surface plot Which functions in SAGE can be used for smoothening the surface plots? |
