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 =
