22 Each of these functions quantizes a signal array by using the following
23 equation:
24
25 X = x(n) n = 0, 1, ...
26 Z = z(n) n = 0, 1, ...
27 = 0 for x(n) < t(0)
28 = k for t(k) ≤ x(n) < t(k+1)
29 = 255 for x(n) ≥ t(255)

33 Each of the functions takes the following arguments:
34
35 dst Output signal array.
36
37
38 src Input signal array.
39
40
41 thresh Array of 256 thresholds.
42
43
44 n Number of samples in the input signal array.
45
46
48 Each of the functions returns MLIB_SUCCESS if successful. Otherwise it
49 returns MLIB_FAILURE.
