Find `k`

largest elements of array

returns the `B`

= maxk(`A`

,`k`

)`k`

largest elements of `A`

.

If

`A`

is a vector, then`maxk`

returns a vector containing the`k`

largest elements of`A`

.If

`A`

is a matrix, then`maxk`

returns a matrix whose columns contain the`k`

largest elements of each column of`A`

.If

`A`

is a multidimensional array, then`maxk`

returns the`k`

largest elements along the first dimension whose size does not equal 1.
