The MATLAB vector data set called wind represents air currents over North America. This example uses a combination of techniques: Read More
Displaying Curl with Stream Ribbons
What Stream Ribbons Can Show
Stream ribbons illustrate direction of flow, similar to stream lines, but can also show rotation about the flow axis by twisting the ribbon-shaped flow line. The streamribbon function enables you to specify a twist angle (in radians) for each vertex in the stream ribbons. Read More

Localize minima and maxima of functions
Let us try to find the local minima and maxima for the function func(x). The interval of interest is [-6 0]. The algorithms are iterative. There are 2 methods to use. The first one decides x in a given interval, and the second one looks for x around an initial guess. To decide the maxima we are looking for an x that minimizes the negative function: -func(x).
