Hi ablaze, Your code has bin2dec trying to convert a string containing the word 'binary'. Try

a = '1011'
bin2dec(a)

Note that if the input is indeed numerical as shown, then

 binary = 1011;
 decimal = bin2dec(num2str(binary));

would work up to 15 bits. After that you're above the maximum integer value that can be stored accurately in a double (see flintmax)

It is indeed much safer to store this binary number as a string, which does not have any limit on the number of bits.
