Convert character vectors that represent numbers to double precision values. You can also convert a cell array of character vectors to a numeric array of the same size. Convert a character vector to a real number. X = str2double('3.1416') X = 3.1416 Convert a character vector when it repr...

Matlab always display double of this magnitude in engineering notation. There's no option to change that, but the number is stored correctly (again for numbers up to 16 bits). You can see the actually value with 테마복사 fprintf('%d\n', B) You've asked for the number to be ...
