A = randi([1 5],,1); Find the unique elements in the vector. Return the index vectors ia and ic. [C,ia,ic] = unique(a); Count the number of times each element in C appears in a. Specify ic as the first input to accumarray and 1 as the second input so that the function counts repeated subscripts in ic Syntax. Y = sort (X) Y = sort (X,dim) Y = sort (___,direction) [Y,I] = sort (___) Description. example.

MATLAB plot with sorted order - Stack Overflow
The easy way to do that, is to express the date in days, [HOST]=year*+month*30+day. then sorting them, and use index as dicuss in previous comments but unfortunately if you have files with the same date need to do next step. the next step is to get only the equal date, then express their time in seconds, I.e. The answer to your question is explained in the SORT documentation: " [B, I] = sort(___) also returns a collection of index vectors for any of the previous syntaxes. I is Missing: null In my case I need to reverse 16bit numbers, so, I've tried three methods: 1) Using fliplr () to reverse as per the suggestions: uint16(bin2dec(fliplr(dec2bin(data,16)))) To test out the speed I decided to try and checksum 12MB of data. Using the above code in my CRC, it took seconds to complete!
Sorting - How can I sort a 2-D array in MATLAB with respect to …
If you are using a MATLAB version newer than Rb, you can take advantage of the "sortrows" function in tables for a simpler workflow: Theme. Copy. >> % suppose 's' is the struct array. 'DOB' is the field that contains date and time. >> T = struct2table (s); % convert the struct array to a table. >> sortedT = sortrows (T, 'DOB'); % C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™. Usage notes and limitations: str must be a string scalar, a character vector, or a cell array containing not more than one character vector
