I'd love to hear about them please post here. Do you use this construct? Can you tell me some applications? Needing to do this once, but I can no longer remember why.

Now I've shown how to use the direct sorting indices of a vector to reverse sort another vector. Now let's compare several variants: B, the regular sorting of B, B sorted by A, and the sorted B rearranged according to the reverse sorting of A newB = sortB(newInd) First we'll work with the variant of B based on sorting from A.

We are now in a position to undo the original sorting of A and apply the rearrange variants of B the same way. The common application of these algorithms is in databases and other computer applications.

Sorting, on the other hand, is the arrangement of data in a specific required order. I can still use the index from sort but in a different way. Searching and Sorting in Matlab AugTopics: Languages Searching is the process of locating a given object or data within a large set of data. Alphanumeric sort of filenames or filepaths, with customizable number format. For symbolic input X that contains complex numbers, sort (X) sorts the complex numbers first by their real parts, then by their imaginary parts to break ties. Suppose instead, I want all my vectors to be sorted the same way that the original A is sorted. The sort function sorts symbolic complex numbers differently from MATLAB floating-point complex numbers. You can see that sorting B according to A (the 3rd row) is distinct from sorting B directly (second row). The main change from v2.5 is a completely new and much more sophisticated clustering algorithm, which we will document soon.

In many cases, and especially for Neuropixels probes, the automated output of Kilosort3 requires minimal manual curation.

Now let's have a look at the variants of the vector B. Welcome to Kilosort3, a MATLAB package for spike sorting electrophysiological data up to 1024 channels. n length(a) if n < 1 s a else s merge( mysort( a(1 : n/2) ). This is a handy trick X I sort(x) Y y(I) plot(X,Y) 'done' categories: Miscellaneous ans done Published with MATLAB 7. You can see that each number in A still corresponds to the same value from B after each vector has been sorted based on A. Merge Sort (in MatLab) function s mysort(a) sort vector a into nodecreasing order. We can use an extra feature of sort to sort x and y, so that x is sorted in ascending order, and we use the change in the order of x to get the corresponding changes in y. Here are the indices required to rearrange A into sortA.Īnd here's a comparison of the original vectors and the ones sorted by the order in A. This function sorts the elements of the vector, array, or variable in ascending lexicographical order. This function is used to sorts the elements in different dimensions of an array and matrix.

To sort multiple additional vectors in the same way as an initial one, we can easily take advantage of the sort index. Matlab sort function is used for internal sorting in all cases like symbolic expressions and functions.
