<p class="para">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 =</p>
<p class="para">0 2 4 6 7
