NUM2STR Convert Numbers To Strings

Section: Array Generation and Manipulations

Usage

Converts an array into its string representation. The general syntax for this function is 
   s = num2str(X)

where s is a string (or string matrix) and X is an array. By default, the num2str function uses 4 digits of precision and an exponent if required. If you want more digits of precision, you can specify the precition via the form 

   s = num2str(X, precision)

where precision is the number of digits to include in the string representation. For more control over the format of the output, you can also specify a format specifier (see printf for more details). 

   s = num2str(X, format)

where format is the specifier string.
