Matlab array of strings

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.Jun 3, 2012 · That was another possibility (convert to a 2-D string, then to cell array) but has the disadvantage that it pads the rows of the string with spaces. – Jason S May 30, 2012 at 14:25 Create Cell Array of Character Vectors. To create a cell array of character vectors, use curly braces, {}, just as you would to create any cell array. For example, use a cell array of character vectors to store a list of names.

Search is same as vectorized. Sorting works where it makes sense, i.e. where objects can be compared like strings. For many years I thought of cell and double arrays as something different. For any input cell whose text does not contain 'bla', “strfind” returns an empty cell. Use “isempty” and “cellfun” with the “find” function to find the empty cells. Theme. Copy. IndexC = strfind (C,'bla'); Index = find (not (cellfun ('isempty',IndexC))) If you are searching for text that is exactly 'bla', then see Jos’ answer.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 ...str = strjoin (C) constructs str by linking the elements of C with a space between consecutive elements. C can be a cell array of character vectors or a string array. example. str = strjoin (C,delimiter) constructs str by linking each element of C with the elements in delimiter. I'm new to MATLAB and I'm struggling to comprehend the subtleties between array-wise and element wise operations.
