Use isdir field of dir output to separate subdirectories and files: d = dir(pathFolder); isub = [d(:).isdir]; %# returns logical vector nameFolds = {d(isub).name}’; You can then remove . and .. nameFolds(ismember(nameFolds,{‘.’,’..’})) = []; You shouldn’t do nameFolds(1:2) = [], since dir output from root directory does not contain those dot-folders. At least on Windows.
According to the documentation of imfill in MATLAB: BW2 = imfill(BW,’holes’); fills holes in the binary image BW. A hole is a set of background pixels that cannot be reached by filling in the background from the edge of the image. Therefore to get the “holes” pixels, make a call to cvFloodFill with the left … Read more
first, you need to find the toolbox that you need. There are many people developing 3rd party toolboxes for Matlab, so there isn’t just one single place where you can find “the image processing toolbox”. That said, a good place to start looking is the Matlab Central which is a Mathworks-run site for exchanging all … Read more
In recent versions of MATLAB, there’s the containers.Map data structure. See MATLAB Map containers for more. This removes some of the restrictions when using STRUCTs. For example c = containers.Map c(‘foo’) = 1 c(‘ not a var name ‘) = 2 keys(c) values(c)
The ndgrid function almost gives the answer, but has one caveat: n output variables must be explicitly defined to call it. Since n is arbitrary, the best way is to use a comma-separated list (generated from a cell array with ncells) to serve as output. The resulting n matrices are then concatenated into the desired … Read more
Consider this solution using the NDGRID function: sets = {[1 2], [1 2], [4 5]}; [x y z] = ndgrid(sets{:}); cartProd = [x(:) y(:) z(:)]; cartProd = 1 1 4 2 1 4 1 2 4 2 2 4 1 1 5 2 1 5 1 2 5 2 2 5 Or if you want … Read more
Use the size() function. >> size(A,2) Ans = 3 The second argument specifies the dimension of which number of elements are required which will be ‘2’ if you want the number of columns. Official documentation.
.mat files contain binary data, so you will not be able to open them easily with a word processor. There are some options for opening them outside of MATLAB: If all you need to do is look at the files, you could obtain Octave, which is a free, but somewhat slower implementation of MATLAB. You … Read more
Introduction The debate on whether bsxfun is better than repmat or vice versa has been going on like forever. In this post, we would try to compare how the different built-ins that ship with MATLAB fight it out against repmat equivalents in terms of their runtime performances and hopefully draw some meaningful conclusions out of … Read more
These are the steps I would take to solve your problem in a vectorized way, starting with a given vector sig: First, threshold the vector to get a vector tsig of zeros and ones (zeroes where the absolute value of the signal drops close enough to zero, ones elsewhere): tsig = (abs(sig) >= eps); %# … Read more
