In addition domain borders can be displayed and superimposed to the plot data. Table of Contents, Get code for this tutorial. Polar Plots (with a little help from Matlab) Matlab provides functions that produce polar plots in appropriate coordinates using magnitudes and angles. frictionless) and irrotational (i. Contour plot is just a way to represent data with two variables, i. If the number of matrix rows equals the vector length, then the plot function plots each matrix column versus the vector. Streamlines follow easily the row wise. A second approach uses Euler's Equations (which the Bernoulli equation is derived from) across the streamlines. You can visualize a vector field by plotting vectors on a regular grid, by plotting a selection of streamlines, or by using a gradient color scheme to illustrate vector and streamline densities. This is because the viscous effects are limited to. Lets say I have channel of length x = 200 and height y = 200.
