Though it stores 11 characters, str is a 1-by-1 string array, or string scalar. If you call length on a string scalar, then the output argument is 1, no matter how many characters it stores. str = "Hello World" ; L = length (str) L = 1. 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. As an alternative, use the str2double function.str2double is suitable when the input argument …Comparing lists of strings. Learn more about strings, cell arrays, permutation, strcmp MATLAB.
