How can I convert this string [0,1,2,3,4,5,6,7,8,9,0xA,0xB] binary?

Hex inputs are:

0xA = 10

0xB = 11

My Goal is to get one long consecutive binary output to look like this:

change it decimal, then to binary, then combine all binary values

'0000 0001 0010 00010'

but with no spaces and continous. Basically make it into a 32bit vector

'00000001001000010'

I have tried this code:

Array = [0,1,2,3,4,5,6,7,8,9,0xa,0xb];
reshape(dec2bin(Array),1,[])
reshape(dec2bin(Array,8),1,[])

I get this Error:

>> untitled4

Error: File: untitled4.m Line: 1 Column: 31

Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax

error. To construct matrices, use brackets instead of parentheses.

Array = [0,1,2,3,4,5,6,7,8,9,0xa,0xb];
reshape(dec2bin(Array),1,[])
ans = '000000001111000011110000001100110011010101010101'
reshape(dec2bin(Array,8),1,[])
ans = '000000000000000000000000000000000000000000000000000000001111000011110000001100110011010101010101'

As you can see, your code runs in R2020b. I just tested on my own copy of R2020a, and it works there as well.

Also a side note: Array is not a string, it is not even a char, it is a uint8 array (which dec2bin probably converts to double internally).

I guess, you are using an older version of Matlab, which does not allow to write hex numbers in the code directly. Then:

HexArray = {'0','1','2','3','4','5','6','7','8','9','a','b'};
DecArray = hex2dec(HexArray);
reshape(dec2bin(DecArray),1,[])
reshape(dec2bin(DecArray,8),1,[])

I thought that as well, but this OP actually did what many didn't: marking the release they use. As that is R2020a, the original code should work as well.
