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. WebUsed in vector analysis to denote gradient operator and its generalizations. Used in numerical analysis to denote backward difference operator. Also called nabla. Not the same as \ [EmptyDownTriangle].

WebThe gradient of a function results then the del operator acts on a scalar producing a vector gradient. The divergence of a function is the dot product of the del operator and a vector valued function producing a scalar. When we use Mathematica to compute Div, we must remember to input the components of a vector. If we wish to find the ...
