I do not like storing the handle values, it becomes a mess when I have a lot of graphs in my figures. Therefore i found another solution. t = 0 : 0.01 : 2 * pi; s = sin(t); c = cos(t); m = -sin(t); hold on; plot(t, s, ‘r’, ‘HandleVisibility’,’off’); % Plotting and telling … Read more
I think it can be as simple as if all(v == v(1)) Another method would be if range(v) == 0
If you just wish to remove the zeros, leaving the non-zeros behind in a, then the very best solution is a(a==0) = []; This deletes the zero elements, using a logical indexing approach in MATLAB. When the index to a vector is a boolean vector of the same length as the vector, then MATLAB can … Read more
Use fflush(stdout) and/or fflush(stderr) to flush the buffer from disp().
Matlab VLFEAT -multiple matching [closed]
The builtin functions are cat, vertcat, and horzcat, found on pages 380-381 of the Octave documentation (v 3.8). They are essentially equivalent to what you have though. octave:5> A = [2 3 4]; octave:6> A = [A; 3 4 5] A = 2 3 4 3 4 5 octave:7> B = [4 5 6]; octave:8> … Read more
Matlab has constants now. The newer (R2008a+) “classdef” style of Matlab OOP lets you define constant class properties. This is probably the best option if you don’t require back-compatibility to old Matlabs. (Or, conversely, is a good reason to abandon back-compatibility.) Define them in a class. classdef MyConstants properties (Constant = true) SECONDS_PER_HOUR = 60*60; … Read more
I always do like that: if ~exist(‘arg1′,’var’) arg1=0; end As said by @Andrey, with this solution you can change the number/order of the arguments of the function, without changing the code. This is not the case with the nargin solution. As said by @yuk, if you want to allow to skip arguments you can do: … Read more
Subscript indices must either be real positive integers or logicals In nearly all cases this error is caused by one of two reasons. Fortunately there is an easy check for this. First of all make sure you are at the line where the error occurs, this can usually be achieved by using dbstop if error … Read more
Another choice is to set the edgeColor and/or lineStyle properties of the surface handle object to none. >> hSurf = surf(X,Y,Z,’EdgeColor’,’none’,’LineStyle’,’none’,’FaceLighting’,’phong’);
