The input range is divided into 2 n evenly spaced intervals. This encoding adheres to the definition for uniform encoding specified in ITU-T Recommendation G.701. Algorithms uencode maps the floating-point input value to an integer value determined by the requirement for 2 n levels of quantization. The integer type of the output depends on the number of quantization levels 2 n and the value of 'SignFlag', which can be one of the following. Input entries outside this range are saturated. Y = uencode(u,n,v, 'SignFlag') maps entries in a multidimensional array of floating-point numbers u whose entries have values in the range to an integer output y. For input entries greater than v, the value of the output of uencode is 2 n – 1.For input entries less than - v, the value of the output of uencode is 0.Elements of the input u outside of the range are treated as overflows and are saturated. The elements of the output y are unsigned integers with magnitudes in the range.
The output y and the input u are arrays of the same size. Inputs can be real or complex, double- or single-precision. N must be an integer between 2 and 32 (inclusive).
