Hi I am getting an error whenever I try to use hexa values in matlab. What should I do to get rid of this issue? I am currently using 2019a and just switched from 2017b hoping to make the code run...
for example when I try 0x1FFFF or 0X1FFFF I keep on getting the following error

Your observation is correct. Before version 2019b hexadecimal and binary values are not recognized by Matlab and a leading 0x or 0b is not recognized. See: https://www.mathworks.com/help/releases/R2020a/matlab/matlab_prog/specify-hexadecimal-and-binary-numbers.html
Either upgrade to at least R2019b or use sscanf , which is much faster than hex2dec.
