Matlab Plot In Loop Error Stack Overflow To plot each point as a dot the plot() line can be changed to plot(pr,r,'.'). using hold on will retain the current plot and in this example add a point on every iteration. the hold on term is typically used to overlay plots on the same axis. in this case the plots being overlaid are single points. I am trying to plot a basic function in matlab, and the plot is appearing in a figure window, but these is no graph in the plot. my previous question was regarding the same issue, but the error was in my faulty understanding of linspace.
Matlab Plot In Loop Error Stack Overflow If you just plot the determinant of (xi − a) (x i − a), you will notice the eigenvalues when the shifted matrix becomes zero. since, you have access to matlab, it is rather easy to compute the eigenvalues of a a to confirm your observations. If you are unable to successfully plot a graph using the plot function in matlab, you can try the following troubleshooting methods: check input data: ensure that the format of the input data is correct, such as data type and dimensions. Hey, i've got a problem plotting a function in matlab. i first run this: format long f = inline (' x.^2'); for i = 0:10 [i (i 1) h (i 1) tid (i 1)] = trapets (f,0,1,2^i); e. Trying to plot a function on matlab, however the graph comes out completely empty. you need to use element wise operation for division: plotting will work fine then. the problem now is that y is a one element array. i want to add here that, the only operation that should be element wise operation is the division in the middle.

When i try to plot the data, i end up with a graph that is all one color or an error message that references the complex values in my data. i have tried interpolating to create a 2d set of values using the griddata () function, however, when applied to my 3d dataset, this returns a 1d vector equal to the z column in my original 3d dataset. Do y(i) = inside the loop, then plot(temp, y) after the loop. if you only want 1 graph, pass something like figure (1). also, take figure out of the loop and instead do: eqn = ((nh^2) (1 nh))*68.045964 == exp(klnvalue(i)); y = max(vpa(solve(eqn, nh))) x = temp(i); plot(x,y) end. When i try to plot it like this: the surface plot doesn't show up. the axes are there but there is no surface plot. however, if for some reason i do a surface plot of a subset of the matrix like this: then it works and the plot shows up. as soon as i increase the number in the brackets to 32 it stops working. Try it in a for loop. if (t(i) >=0 && t(i) <= td) c o(t(i))=0;.
