I have a predefined array of 20 position which correspond to 20 joint out of my body. The joints are marked with string values (e.g. 'left_knee', 'head', 'left_eye', etc.). I want to refer to a certain value within the array by using the attached string value. For example I want to store the position of the observed joints.String arrays are supported throughout MATLAB and MathWorks® products. Functions that accept character arrays (and cell arrays of character vectors) as inputs also accept string arrays. Represent Text with Character Vectors. To store a 1-by-n sequence of characters as a character vector, using the char data type, enclose it in single quotes.Parse a cell array of strings without looping.

I wish to extract the first and third row as numbers to be assigned to a numerical matrix, while extracting the second row as a row of strings, which are to be assigned to another matrix. The idea is to create a matrix Event_Vals, which consists of …By default, the join function combines strings along the last dimension with a size that does not equal 1. To combine the strings along the first dimension, specify it as an additional input argument. newStr = join (str,1) newStr = 1x2 string "Carlos Ella Diana" "Sada Olsen Lee". You can represent text in MATLAB ® using string arrays. Each element of a string array stores a sequence of characters. The sequences can have different lengths without padding, such as "yes" and "no". A string array that has only one element is also called a string scalar. Description. 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 ... 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.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 ...In fact I would like to save the whole of cell array "features_score" in to *xls/csv file, in which first column of file is for strings and the second column is numeric values. beside your solution, there is another problem that some strings do not fit in one row and take 2 rows...If A is a cell array of character vectors, then B is a string array that has the same size.

The input can include spaces, commas, and semicolons to indicate separate elements. If str2num cannot parse the input as numeric values, then it returns an empty matrix. The str2num function does not convert cell arrays or nonscalar string arrays, and is ... The input array str can be a string array, character vector, or cell array of character vectors. If str is a string array, then so is newStr. Otherwise, newStr is a cell array of character vectors. newStr does not include the whitespace characters from str. Split, Join, and Sort String Array. MATLAB provides a rich set of functions to work with string arrays. For example, you can use the split, join, and sort functions to rearrange the string array names so that the names are in alphabetical order by last name.. Split names on the space characters. Splitting changes names from a 5-by-1 string array to a 5-by-2 …EDIT: The backspace character is handled differently according to the final "usage" of the string. For instance, it works perfectly when displaying the string in the terminal; however, printing the string to a file does not remove the comma.

The problem is that, inside the 'for' loop, my iterator is considered a 'cell' rather than a string. ... Isn't there a more elegant way to iterate over the cell array of strings to directly getting the cells content without calling str{1}? -- edit -- nevermind, ...If both s1 and s2 are character arrays with multiple rows, then s1 and s2 can have different numbers of rows. When comparing a nonscalar cell array of character vectors or a string array to a multirow character array, the cell array or string array must be a column vector with the same number of rows as the character array. This MATLAB function returns a string with no characters. If the size of any dimension is 0, then str is an empty array.. If the size of any dimension is negative, then strings treats it as 0.. Beyond the second dimension, strings ignores trailing dimensions with a size of 1.For example, strings(3,1,1,1) produces a 3-by-1 vector of strings with no characters.When the input argument is a string array, the double function treats each element as the representation of a floating-point value. However, when the input is a character array, double instead converts each character to a number representing its Unicode® value.

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 ...MATLAB® provides string arrays to store pieces of text. Each element of a string array contains a 1-by-n sequence of characters. You can create a string using double quotes. …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 ...When the input argument is a string array, the double function treats each element as the representation of a floating-point value.
