fyi, a function in Mathematica is defined using _ as in f[w_,x_,y_,z_]:=. These functions usually have an enormous number of diâµerent options. For example, to plot a circle: To assign values to variables, use -> rather than an equals sign. 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 ( â¦ In Mathematica, the Fit function takes a list of points, a list of expressions, and a list of independent variables, and determines which linear combination of the given expressions produces the best fit to the data. Plotting a parameterized curve in Octave is trivial. In[5]:= Plot x, x^2, x^3 , x, 0, 2 Out[5]= 0.5 1.0 1.5 2.0 2 4 6 8 Notice that we have two sets of lists in the plot directly above, : the first set enumerates the list of functions to be plotted, the second list delineates the plotting parameters (i.e., plotting with This section is dedicated to the description of the diâµerent plotting functions available in Mathematica. value of the ï¬tted parameters, etc.). The relation between the parameter sets is given in the Details section. In effect, the regular plot() function already gives a plot of a parametrized function. Is there a way you can normalize your function first? 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 . Assigning and Inserting Variables or Parameters. For example, To insert a set of parameters to a function use /. The Mathematica commands in this tutorial are all written in bold black font, while Mathematica output is in normal font. Sin[x], Exp[x], Pi or Infinity. btw, your functions always seem to generate very large values: N@f[1, 1, 1, 1] gives 1.9489499245*10^21714 which is really a large number. Both of these plot types work best on functions ( elds) that are large within some central region, dying out with distance. All Mathematica functions start with a capital letter, eg. Itâs just that using x as the parameter is the most typical use. If you want ... linePlot= Plot@lineFit,8x,-5,5
