Sorted by: 8. You cannot do this with standard Matlab arrays. A string is really just a vector of characters in Matlab. And you cannot have a matrix with rows of different lengths. You can, however, use a cell array: userinput= {'AJ48 NOT'; 'AH43 MANA'; 'AS33 NEWEF'}; disp (userinput {1}); Be aware that there are many situations ...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 …1. Use curly braces to refer to the contents of a cell: data {1} = 'hello'; %// assign a string as contents of the cell. The notation data (1) refers to the cell itself, not to its contents. So you could also use (but it's unnecessarily cumbersome here): data (1) = {'hello'}; %// assign a cell to a cell. More information about indexing into ...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 ...To enable code that works with strings to accept character arrays as inputs, add a call to convertCharsToStrings 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 convertCharsToStrings . Convert a numeric array to a character array. A = [77 65 84 76 65 66]; C = char (A) C = 'MATLAB'. The integers from 32 to 127 correspond to printable ASCII characters.
