Is there any way to set specific bits in a binary number in Matlab.
I'm currently converting a number into a binary string using the dec2bin function, I then want to change the lower 6 bits.
ie
dec2bin(3124)
ans = 110000110100
I need to set the lower 6 bits to be 100000, resulting in:
ans = 110000100000
Is this possible?
Thanks, Ben

a = dec2bin(3124)
a(end - (5:-1:0)) = '100000'
