uencode Performs uniform quantization of the input into 2^n levels y=uencode(u,n,v,'signflag') Uniformly quantizes the input vector or n-dimensional array u into 2^n levels in the interval [-v,v] If v is not specified, its default value is 1 'signflag' is a string that determines the nature of the quantization If signflag='unsigned' then y contains unsigned integers in the range [0,2^n-1] corresponding to the 2^n levels If signflag='unsigned' then y contains signed integers in the range [-2^(n-1),2^(n-1)-1] corresponding to the 2^n levels The size of the integers in y in bits(8,16, or 32) depends on the value of n If the input lies beyond +/- v it is saturated Example y=uencode(-1:0.5:1,3) y = 0 2 4 6 7 Author Ankur Mallick References [1] International Telecommunication Union.
