Copy. legendCell = cellstr (num2str (dope, 'N=%-d')); legend (legendCell)Accepted Answer: Fangjun Jiang. As the title says, I'm looking to concatenate character strings with a delimiter. For example, take 'sample','abc','1234','12' and combine them into 'sample_abc_1234_12'. I've written my own simple function for this, but I was just curious if there's a built-in function (similar to strcat) that accomplishes the ...cellfun and arrayfun can add significant overhead. There are many ways to convert a numeric array to a cell array of strings. The three highest-performance solutions are very similar in terms of performance: Looping to assign cell elements. n4 = length (Keyset); tmp4 = cell (n4,1); for i4 = 1:n4 tmp4 {i4} = sprintf ('%i',Keyset (i4)); end ... Learn how to create string arrays from variables, character vectors, or numeric arrays using the string function or the [] operator. String arrays store pieces of text and provide functions for working with text as data. Read Dates and Times from Files. Many files, such as spreadsheets and text files, store dates and times as text. If the dates and times are in recognized formats, then functions such as readcell, readvars, and readtable can read them and automatically convert them to datetime or duration arrays.. For example, the CSV file outages.csv is a sample file that …Specify multiple delimiters in a string array, cell array of character vectors, or pattern array. The split function splits str on the elements of delimiter . The order in which delimiters …Copy. join (erase (string (Exampletable {:, :}), "'"), '', 2) which: extracts the content of the table as a categorical array. converts the categorical array into a string array. erases the ' from the string array. joins the string array across the column. But again, a better approach would be to import the data correctly in the first place, so ...1. It depends how you want to split it. For your case (before your edit with square brackets) it's very easy: A = ['12345'; '67890'; '12345'] B = A (:,1:3) C = A (:,4:end) For more complicated cases, have a look at strsplit (a quite new function, otherwise available at File Exchange) Actually you mentioned you'd have a cell array, and also if ...T = combinations (A1,...,An) generates all element combinations of input arrays A1,...,An, where each row of the output table T is a combination. These combinations are the same as the Cartesian product of n sets of elements where the n sets are represented by the input arrays A1,...,An. The number of rows in T is the product of the number of ...Creation. You can create a string scalar by enclosing a piece of text in double quotes. str = "Hello, world". str = "Hello, world". To create a string array, you can concatenate string scalars using square brackets, just as you can concatenate numbers into a numeric array. The old string and new string inputs can be single strings or tall arrays of strings with the same size. For more information, see Tall Arrays for Out-of-Memory Data . C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™.I have two cell arrays of strings, and I want to check if they contain the same strings (they do not have to be in the same order, nor do we know if they are of the same lengths). ...

And to reference one of the strings. k = strfind (str,pat) searches str for occurrences of pat. The output, k, indicates the starting index of each occurrence of pat in str. If pat is not found, then strfind returns an empty array, []. The strfind function executes a case-sensitive search. If str is a character vector or a string scalar, then strfind returns a vector of type double. Learn how to create string arrays from variables, character vectors, or numeric arrays using the string function or the [] operator. String arrays store pieces of text and provide …I'm new to MATLAB and I'm struggling to comprehend the subtleties between array-wise and element wise operations.

Find the treasures in MATLAB Central and discover how the community can help you! Start Hunting! An Error ...2. Rather than turning into a matrix you can just operate on the cell array since it seems like you have different-sized data in each element which makes it nearly impossible to combine into a character array: Use cellfun to call strsplit on each entry. out = cellfun (@strsplit, data, 'uniformoutput', false); Just use regexp to split the string ...You can prepend a char array to a cell array in the same way how cell arrays are combined. In the similar way, you can also combine a cell array of char with a string array or a simple char array with a string array which will result in a string array though. The datatype can be changed later to a cell array of char if required using cellstr.Read Dates and Times from Files. Many files, such as spreadsheets and text files, store dates and times as text.
