<para>
Uniformly decodes the input vector or n-dimensional array of integers u with peak values +/- v
If u has only positive values, the range of integers is assumed to be [0,2^n-1]
If u has positive and negative values the range of integers is assumed to be [-2^(n-1),2^(n-1)-1]
If v is not specified, its default value is 1
If saturatemode='wrap' the output is wrapped using modulo arithmetic if overflow occurs
If saturatemode='saturate' the output is saturated if overflow accors
Example
u = int8([-1 1 2 -5]);
ysat = udecode(u,3)
ysat =
