Remove xticks but keep xticklabels in MATLAB
Try modifying the TickLength property: set(gca, ‘Ticklength’, [0 0])

There’s no way I know of within the expression of the anonymous function to have it select which output to return from a function with multiple possible output arguments. However, you can return multiple outputs when you evaluate the anonymous function. Here’s an example using the function MAX: >> data = [1 3 2 5 … Read more
How about date = datestr(unix_time/86400 + datenum(1970,1,1)) if unix_time is given in seconds, unix_time/86400 will give the number of days since Jan. 1st 1970. Add to that the offset used by Matlab’s datenum (datenum(0000,1,1) == 1), and you have the amount of days since Jan. 1st, 0000. This can be easily converted to human-readable form … Read more
To fit a curve onto a set of points, we can use ordinary least-squares regression. There is a solution page by MathWorks describing the process. As an example, let’s start with some random data: % some 3d points data = mvnrnd([0 0 0], [1 -0.5 0.8; -0.5 1.1 0; 0.8 0 1], 50); As @BasSwinckels … Read more
Well, there are a few ways how multiple data series can be displayed in the same figure. I will use a little example data set, together with corresponding colors: %% Data t = 0:100; f1 = 0.3; f2 = 0.07; u1 = sin(f1*t); cu1 = ‘r’; %red u2 = cos(f2*t); cu2 = ‘b’; %blue v1 … Read more
Matlab has a function called printmat in the Control Systems toolbox. It’s in the directory “ctrlobsolete“, so we can assume that it is considered “obsolete”, but it still works. The help text is: >> help printmat printmat Print matrix with labels. printmat(A,NAME,RLAB,CLAB) prints the matrix A with the row labels RLAB and column labels CLAB. … Read more
Look at the filter function. If you just need a 1-pole low-pass filter, it’s xfilt = filter(a, [1 a-1], x); where a = T/τ, T = the time between samples, and τ (tau) is the filter time constant. Here’s the corresponding high-pass filter: xfilt = filter([1-a a-1],[1 a-1], x); If you need to design a … Read more
MATLAB has access to Java: >> a=java.util.LinkedList; >> li=a.listIterator; >> li.add(2); >> li.add(int8(77)); >> li.add(77); >> li.add(boolean(true)); >> li.add(‘Mr. Bill’); >> li.previous(); >> li.add([1 2 3 4 5]); >> a a = [2.0, 77, 77.0, true, [D@66a917, Mr. Bill] >> a.get(4) ans = 1 2 3 4 5 The one downside of this approach is … Read more
This worked for me: figure(‘units’,’normalized’,’outerposition’,[0 0 1 1]) or for current figure: set(gcf,’units’,’normalized’,’outerposition’,[0 0 1 1]) I have also used MAXIMIZE function on FileExchange that uses java. This is true maximization.
MATLAB Compiler encrypts and archives your MATLAB code (which remains as MATLAB .m code), and packages it in a thin executable (either .exe or .dll) wrapper. This is delivered to the end user along with the MATLAB Compiler Runtime (MCR). If you wish, the MCR can be packaged within the executable as well. The MCR … Read more
