str = sprintf(format, A, …)applies the format to all elements of array A and any additional array arguments in column order, and returns the results to string str. [str, errmsg] = sprintf(format, A, …)returns
When the input argument is a string array, thedoublefunction treats each element as the representation of a floating-point value. However, when the input is a character array,doubleinstead converts each character to a number representing its Unicode® value. As an alternative, use thestr2double...
To return formatted text as a string, specify formatSpec as a string instead of a character vector when you call the sprintf function. Convert data and return the result as a string. Get formatSpec = "The current time is: %d:%d %s"; A1 = 11; A2 = 20; A3 = 'a.m.'; str = ...
For each numeric conversion specifier in formatSpec, the textscan function returns a K-by-1 MATLAB numeric vector to the output cell array, C, where K is the number of times that textscan finds a field matching the specifier. For each text conversion specifier (%s, %q, or %[...]) ...
