Link. Open in MATLAB Online. You might need to share some more details about your table, but you should be able to use the unique function. Theme. Copy. % Make some pretend data, which is 8 rows with 4 unique ones. tbl = array2table ( [magic (4); magic (4)]); % Find the unique rows, along with indices for identifying the duplicates.for j = 2:102. for i = 2:length (nameData) S (n).name = nameData {i,j}; S (n).frequency = 1; n = n+1; end. end. However, I need to find duplicate strings in this array, and find information about them. Basically, I am collecting a database of strings and if I run across a duplicate, increase the frequency of that string rather than adding it to ...

Based on Abhinav's answer and some tests, I wrote a function which is ALWAYS faster than repmat ()! It uses the same parameters, except for the first parameter which must be a vector and not a matrix. function vec = repvec( vec, rows, cols ) %REPVEC Replicates a vector. % Replicates a vector rows times in dim1 and cols …To enable your existing code to accept string arrays as input, add a call to convertStringsToChars at the beginning of your code. For example, if you have defined a function myFunc that accepts three input arguments, process all three inputs using convertStringsToChars .how can I create a matrix based on the vector v = [12.56, 65.23, 5.67], which is repeated 20 times? So that the matrix M look like:

You will be provided a string (s = 'string1_') a starting point (num1 = 6) (always bigger than or equal to zero) and n (n = 3) (always bigger than or equal to 1) You will return following in sequence;Description. case case_expression, end evaluates an expression and chooses to execute one of several groups of statements. Each choice is a case. The switch block tests each case until one of the case expressions is true. A case is true when: For numbers, case_expression == switch_expression. == 1.

Feb 15, 2024 · It provides a flexible way to create repeated patterns within an array, allowing for efficient handling of repetitive tasks in data processing and analysis. The repelem() function in MATLAB has two primary syntaxes: Basic Syntax: output = repelem(v, n) Where: v: The input vector or scalar to be repeated. n: The number of times each element of v ... end executes a group of statements in a loop for a specified number of times. values has one of the following forms: initVal:endVal — Increment the index variable from initVal to endVal by 1, and repeat execution of statements until index is greater than endVal. initVal:step:endVal — Increment index by the value step on each iteration, or ...May 21, 2012 · You should call the cell's content via str{1} as follows to make it correct: fprintf('%s',str{1}); Here's a more sophisticated example on printing contents of cell arrays. This really bothers me every time I work with a cell array of strings. Isn't there a more elegant way to iterate over the cell array of strings to directly getting the ... This MATLAB function formats the data in arrays A1,...,An using the formatting operators specified by formatSpec and returns the resulting text in str. ... To return multiple pieces of formatted text as a string array or a cell array of character vectors, use the compose function. [str,errmsg] = sprintf ...For the carsmall data used in the other comparisons, histc was actually 1.33x faster than histcounts in r2019b and 1.22 x faster on r2020a (matlab online). On both machines I repeated the 10000-rep analysis 3 times and the final results were all within +/-0.02 of what's reported.

Discussion. The switch statement syntax is a means of conditionally executing code. In particular, switch executes one set of statements selected from an arbitrary number of alternatives. Each alternative is called a case, and consists of: The case statement. One or more case expressions. One or more statements.

function [result] = repcolumn(A, n) %n - how many times each column from A should be repeated. [rows columns] = size(A); result = repmat(A(:,1),1,n); for i = 2:columns. result = [result,repmat(A(:,i),1,n)]; end. end. There must be an easier way but it does the job.

Hi. I want the user to input an arbitrary number, and then set up a for loop that asks the question "Enter a string" as many times as the user indicated above with the first input. I th...To programmatically exit the loop, use a break statement. To skip the rest of the instructions in the loop and begin the next iteration, use a continue statement.. Avoid assigning a value to the index variable within the loop statements. The for statement overrides any changes made to index within the loop.. To iterate over the values of a single column vector, first transpose it to create a ...For strings you can just write "abc" * 3, which works via StringOps and uses a StringBuffer behind the scenes.. For characters I think your solution is pretty reasonable, although char.toString * n is arguably clearer. Do you have any reason to suspect the List.fill version isn't efficient enough for your needs? You could write your own method that would use a StringBuffer (similar to * on ...I have a string of text (hexadecimal) collected from hardware, and within the string are multiple instances of noise.

Each element of a character array stores only one character, so (until the string class was introduced) the only way to store multiple characters using a scalar index (as the question poses) is to use a cell array. From that persepctive it is not a "workaround", it is the correct solution for versions of MATLAB before R2016b.

Each element of n specifies the number of times to repeat the corresponding element of v. hyundai sonata headlight fuse location I understood from your question that the desired result '12345' was a string, not a number (otherwise use Shai's answer less the num2str part). So you want to assign a string to the first element of a variable c?If c has to store other strings of possibly different lengths, c should be a cell array; and you'd just do c{1} = b - Luis MendoThe simplest way to repeat a string in Python is with the * operator. Use the operator on a string to repeat the string a provided number of times. The syntax for the operation is: result = string * number.
