WebPlotting data in Matlab is simple. For example, to plot two functions sin x and cos x on the interval 0<10, type in: t = 0:.1:10; x=cos (t); y=sin (2*t); plot (t,x,t,y) matlab lets you edit and annotate a graph directly from the …
WebApr 24, 2024 · Accepted Answer: KSSV. Greetings all, Please correct me if I am wrong on any of this, but I am trying to plot a damped/attenuating sine wave of the form y (x,t)=Ae^-alpha (x) * sin (wt-Bx + phi). Granted the sin is not in the exponential, I've been trying to code this up knowing that travelling waves have spatial as well as temporal dimensions ... WebApr 11, 2024 · I suggest using the symbolic mathematics toolbox which provides functions for solving, plotting, and manipulating symbolic math equations. " u(x, y) " seems like a bivariate function. To plot such a function, have a look at the " Generate surfaces z = f ( x , y ) without meshgrid " section of the following document:
Weby=linspace (0,3,7); Note that the last form will make it easy for you to produce a finer graph of your function (since plot by default will draw you a piecewise linear function, i.e. connect the points with line segments). So … WebIf you're using MATLAB R2024b, then you can use fimplicit. If you don't then you can use both fplot and plot as an alternative. Both, however, need an explicit form. The code for the two latter is then: for fplot: for …
WebMar 20, 2014 · We can use Matlab's polar command to plot the graph of this equation on [ 0, 2 π]. First, use Matlab's linspace to generate 100 equally spaced points on the interval [ 0, 2 π], then generate the corresponding r -values. Semicolons are used to suppress the output. >> theta=linspace (0,2*pi); >> r=cos (2*theta); Now use Matlab's polar command.
