If your existing MATLAB code expects a serial date number or date vector, use the . hexStr = dec2hex(D) returns the hexadecimal,or base-16, representation of the number D.The output argument hexStr is a character vector that represents hexadecimal digits using the characters 0-9 and A-F.. binStr = dec2bin(D) returns the binary, orbase-2, representation of the number D.The output argument binStr is a character vector that represents binary digits using the characters '0' and '1'.. . The input can include spaces, commas, and semicolons to indicate separate elements. If wchar_t is four bytes long, casting it to unsigned short (two bytes) just means you are treating it as an array of twice as many elements (where every-other one is a null character, since you are splitting the wchar_ts in half). convertCharsToStrings. This could be done as follows: convert A to double to produce each character's ASCII code, and then subtract the code of character '0' to obtain the desired numbers. example. For example, if n is 12, then dec2base represents the numbers 9, 10, and 11 using the characters '9', 'A', and 'B', and represents the number 12 as the character sequence s = num2str (A,precision) converts fi object A to a character array representation using the number of digits of precision specified by precision.
