Hi there I want to write some hexadecimal values in matlab for example
// Add TOW-count message into HOW
if (iwrd==1)
sbfwrd |= ((tow&0x1FFFFUL)<<13);
// Compute checksum
sbfwrd |= (prevwrd<<30) & 0xC0000000UL; // 2 LSBs of the previous transmitted word
nib = ((iwrd==1)||(iwrd==9))?1:0; // Non-information bearing bits for word 2 and 10
chan->dwrd[iwrd] = computeChecksum(sbfwrd, nib);

0x1FFFFu32
The C code is a bit weak in that it assumes unsigned long is 32 bits.

Starting in R2019b, you can write hexadecimal and binary values as literals using an appropriate prefix as notation. For example, 0x2A is a literal that specifies 42—and MATLAB stores it as a number, not as text.
So the reason for the difference between the r2019b system and your R2017b system is that MATLAB was improved as of R2019b to support hexadecimal constants.
Which is why earlier I said "in your version" of MATLAB that hex2dec and sscanf were your available choices.
