WebJul 31, 2013 · Matlab computes the gradient differently for interior rows and border rows (the same is true for the columns of course). At the borders, it is a simple forward difference gradY(1) = row(2) - row(1). The gradient for interior rows is computed by the central difference gradY(2) = (row(3) - row(1)) / 2. WebMar 21, 2012 · Level curves and surfaces can be plotted in Mathematica. These are the constant-value regions of a particular function. The command behaves very much like the Plot and VectorPlot command. The result of a standard ContourPlot command will show up color-coded. Warm colors are large values and cool colors are small values.
