can you convert this code to matlab code?

bit=6;

mult = 256 / (2^bits)

mask = 2^(8 - bits) - 1 prev_sum = 0

for x = 1 to width for

y = 1 to height

value = img[x, y]

if value >> bits != mask:

prev_sum = value + (prev_sum & mask)

else:

prev_sum = value res[x, y] = (prev_sum >> (8 - bits)) * mult
