implicit_plot

Maxima Function

Calling Sequence

implicit_plot (expr, x_range, y_range)
implicit_plot([expr_1,...,expr_n],x_range,y_range)

Description

Displays a plot of one or more expressions in implicit form. expr is the expression to be plotted, x_range the range of the horizontal axis and y_range the range of vertical axis. implicit_plot only works with the gnuplot driver. implicit_plot respects global setting for the gnuplot driver set by the set_plot_option function. Options can also be passed to implicit_plot function as optional arguments.

implicit_plot works by tracking sign changes on the area given by x_range and y_range and can fail for complicated expressions.

load(implicit_plot) loads this function.

Example:

(%i1) implicit_plot (x^2 = y^3 - 3*y + 1, [x, -4, 4], [y, -4, 4],
 [gnuplot_preamble, "set zeroaxis"]);
