median
              Compute the median value of the elements of x.
 When the elements of x are sorted, say
 s = sort (x), the median is defined as
 $$
 {\rm median} (x) =
   \cases{s(\lceil N/2\rceil), & $N$ odd;\cr
           (s(N/2)+s(N/2+1))/2, & $N$ even.}
 $$
 If x is an array, then median (x) operates along the
 first non-singleton dimension of x.
 The optional variable dim forces median to operate over the
 specified dimension, which must be a positive integer-valued number.
 Specifying any singleton dimension in x, including any dimension
 exceeding ndims (x), will result in a median equal to x.
 Specifying the dimensions as  vecdim, a vector of non-repeating
 dimensions, will return the median over the array slice defined by
 vecdim.  If vecdim indexes all dimensions of x, then it is
 equivalent to the option "all".  Any dimension in vecdim
 greater than ndims (x) is ignored.
 Specifying the dimension as "all" will force median to
 operate on all elements of x, and is equivalent to
 median (x(:)).
 median (…, outtype) returns the median with a specified
 data type, using any of the input arguments in the previous syntaxes.
 outtype can take the following values:
"default"Output is of type double, unless the input is single in which case the output is of type single.
"double"Output is of type double.
"native". Output is of the same type as the input (class (x)), unless the
 input is logical in which case the output is of type double.
 
 The optional variable nanflag specifies whether to include or exclude
 NaN values from the calculation using any of the previously specified input
 argument combinations.  The default value for nanflag is
 "includenan" which keeps NaN values in the calculation.  To
 exclude NaN values set the value of nanflag to "omitnan".
 The output will still contain NaN values if x consists of all NaN
 values in the operating dimension.
