Aug 29, 2014 · plot ( [X (1) X (end), [k k] ) would do the job visually if there isn't a reason you need to have a point for every value of your X time series. Plotting e.g. 1000 points to define a horizontal line is unlikely to result in any kind of performance hit, but is a little un-necessary when 2 points would do just as well.

Apologies I am relativey new to using Matlab. I am trying to make a plot of these variables (g versus omega). g is a constant value while ...

Add a dotted vertical line and label to each plot by passing the axes to the xline function. tiledlayout (2,1) ax1 =nexttile; x = linspace (0,10,200); y1 = cos (x); plot (ax1,x,y1) ax2 = nexttile; y2 = sin (x); plot (ax2,x,y2) xline (ax1,pi/2, ':', 'cos (\pi/2)=0' ); xline (ax2,pi, ':', 'sin (\pi)=0' );

17.09.2016 · Sometime in your years of using MATLAB you probably ran across ones () function but forgot about it. You need to use it so that, for each value of x, you have a value for Z. Here is the correct way to do it. x = [1 : 0.5 : 10] y = x .* 4. % Now declare a constant array Z. % with one element for each element of x. Z = 4 * ones (1, length (x));

04.02.2015 · MATLAB's plotting works on a point-by-point basis from the vectors you give. So to create a horizontal line, you need to varying x while keeping y constant and vice-versa for vertical lines: xh = [0,10]; yh = [245,245]; % constant xv = [5,5]; % constant yv = [0,245*2]; plot (xh,yh,xv,yv); Share.

If one of X or Y is a scalar and the other is either a scalar or a vector, then the plot function plots discrete points.

Plot a Horizontal Line Using the yline () Function in MATLAB To create a horizontal line, we can use the Matlab built-in function yline (), which plots a horizontal line with a constant vertical value. For example, let’s plot a horizontal line on a specific vertical position on a graph. See the code below. yline(2) Output:

17.09.2016 · right i forgot i need 15 lines of code to make matlab plot a fregin constant YEA! awesome software! And they wonder why people don't want to us matlab anymore and why schools are now teaching mathematica and what you have there is in no way shape or form the correct way to plot a constant.

yline( y ) creates a horizontal line at one or more y-coordinates in the current axes. For example, yline(2) creates a line at y=2 .

Description. xline (x) creates a vertical line at one or more x -coordinates in the current axes. For example, xline (2) creates a line at x=2. xline (x,LineSpec) specifies the line style, the line color, or both. For example, xline ( [12 20 33],'--b') creates three dashed blue lines.
