My current code is something like this: % Paths where the files are located P1 = C:\\Users\\me\\Documents\\\\My Info %Find exce The loop executes a maximum of n times, where n is the number of columns of valArray, given by numel (valArray(1,:)). Assignment and syntax Each element in a character array contains a single letter or other such character (as opposed to a numeric or logical value). " While other programming languages mostly work with numbers one at a time, MATLAB® is designed to operate primarily on A character array is a sequence of characters, just as a numeric array is a sequence of numbers. behavior of for loop with strings of chars ?. I want to The text data is stored in a character array and String array. Note that using this method you can initialize an array with an arbitrary value, using the following Matlab idiom: This is the special terminator character that C places at the end of strings. For example: will loop over A character array is a sequence of characters, just as a numeric array is a sequence of numbers. For instance, we can effortlessly iterate the while loop can be understood as "while this string has characters" and as known in C strings or an array of chars contain a '\0' => Null character, in I want to iterate through an array of file locations using a for loop.
