M = mode (A) returns the most frequent element in the categorical vector A. If A is a matrix, mode (A) returns a row vector with the most frequent element from each column. For multidimensional arrays, mode (A) operates along the first non-singleton dimension. B is also a categorical array with the same categories as A. For multiple elements with the same maximum frequency along the operating dimension, the element from the category that occurs first in A is returned.

[M, F] = mode (A) also returns a numeric array F, which has the same size as M and it contains the number of occurrences of each corresponding element of M.

[M, F, C] = mode (A) also returns a cell array C, which has the same size as M and each element is a sorted categorical vector of all the values with the same maximum frequency of the corresponding element of M.

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

B = mode (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 = mode (A, [], 'all') operates on all dimensions and returns the most frequent element in A.
