Bit setting a binary number

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

[Andrei Bobrov]

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

a(end - 5:end)) = '100000'
