out = head (A) ¶out = head (A, k) ¶Get first K rows of an array.
Returns the array A, subsetted to its first k rows. This means
subsetting it to the first (min (k, size (A, 1))) elements along
dimension 1, and leaving all other dimensions unrestricted.
A is the array to subset.
k is the number of rows to get. k defaults to 8 if it is omitted or empty.
If there are less than k rows in A, returns all rows.
Returns an array of the same type as A, unless ()-indexing A produces an array of a different type, in which case it returns that type.
