卷积码（2,1,7）编码和4比特电平量化(（2,1,7）encoder)

The Matlab function RGB() converts a color index (whole number from 1-21), English name of a color (string), or RGB triple with whole number components in {0, 1, ..., 255} into an RGB triple with real-valued components in [0,1]. RGB() allows the user to access a set of 21 colors via their common English names. For eight of these colors that have more than one common name, the program accepts alternative names, reducing the memory burden on the user.
