------------------------------------------------------- SYMBOLIC CONVERSION BETWEEN COORDINATE SYSTEMS: I have a spatial scalar function expressed in spherical coordinates. How can I get iso-surfaces ( or iso-contours for 2D cuts), if the usual contouring routines assume that your function is expressed in cartesian coordinates? I also need to plot the vectorfield produced by the gradient of this function. Although the `VectorAnalysis` package allows me to obtain the gradient, I'm stuck with the conversion of coordinates problem when attempting to use the PlotVectorField command. ---------------------------------------------------------
