B = median (A) returns the median of the elements in ordinal categorical vector A. If A is a matrix, median (A) returns a row vector with the median element from each column. For multidimensional arrays, median (A) operates along the first non-singleton dimension. B is also ordinal with the same ordered categories as A. For even number of elements along the operating dimension, the returned median value is either the midway category between the two middle elements or the larger of the two categories midway between the two middle elements.

B = median (A, dim) operates along the dimension specified by dim.

B = median (A, vecdim) operates on all the elements contained in the dimensions specified by vecdim, which must be a numeric vector of non-repeating positive integers. Any values in vecdim indexing dimensions larger that the actual array A are ignored.

C = median (A, [], 'all') operates on all dimensions and returns the median element in A.

C = median (…, missingflag) specifies how to handle undefined elements in any of the previous syntaxes. missingflag must be a character vector or a string scalar with one of the following values:

• 'omitundefined' ignores all undefined elements and returns the median of the remaining elements. If all elements along the operating dimension are undefined, then it returns an undefined element. 'omitnan' may also be used as equivalent to 'omitundefined'.
• 'includeundefined', which is the default, returns an undefined element if there any undefined elements along the operating dimension. 'includenan' may also be used as equivalent to 'includeundefined'.
