Level Curves and Contour Plots Level curves and contour plots are another way of visualizing functions of two variables If you have seen a topographic map then you have seen a contour plot Example To illustrate this we first draw the graph of z = x2 y2 On this graph we draw contours, which are curves at a fixed height z = constantContour3 plots level curves (contour lines) of the matrix z at a Z level corresponding to each contour This is in contrast to contour which plots all of the contour lines at the same Z level and produces a 2D plot The level curves are taken from the contour matrix c computed by contourc for the same arguments;Contour plots An alternative method to representing multivariable functions with a twodimensional input and a onedimensional output, contour maps involve drawing purely in the input space Created by Grant Sanderson This is the currently selected item
