fyi, a function in Mathematica is defined using _ as in f[w_,x_,y_,z_]:=. Mathematica treats the Interpolating Function like a numerically defined function, so you can plot it, numerically integrate it, etc. Fortunately, many examples in electromagnetism have that property. The Mathematica commands in this tutorial are all written in bold black font, while Mathematica output is in normal font. This section is dedicated to the description of the diâµerent plotting functions available in Mathematica. This video tutorial covers basic plotting of functions using Mathematica. Choose the type of plot desired, supply the values of the parameters which are not selected as free variables, and click "Evaluate." Assigning and Inserting Variables or Parameters. The relation between the parameter sets is given in the Details section. The Mathematica commands in this tutorial are all written in bold black font, while Mathematica output is in normal font. Mathematica also provides a ContourPlot3D function for three-dimensional contour plots, as well as a VectorPlot3D function for 3-D vector plots. Nickalls found a set of parameters that do a better job. Finally, you can copy and paste all commands into your Mathematica notebook, change the parameters, and run them because the tutorial is under the terms of the GNU General Public License . These functions usually have an enormous number of diâµerent options. If you want ... linePlot= Plot@lineFit,8x,-5,5
