APPENDNHV

=APPENDNHV(ai,a,hv,i)

ai
first array or initial array
a
group of arrays between () (array1,array2,...,arrayN)
hv
string for direction, only "h" or "v"
i
index, ignored,0 or 1 appends ai to the whole group of arrays, i>1 indexes inside the group arrays a

APPENDNHV appends N arrays horizontally or vertically.

APPENDNHV !! recursive !! appends N arrays horizontally or vertically , calls the other 2 recursive APPEND2H and APPEND2V .
Uses the second syntax of INDEX, INDEX(reference, row_num, [column_num], [area_num]) , so carrys its restrictions (reference argument instead of arrays, arrays should be in the same spreadsheet).
It is a single formula for both directions and for that has an extra argument hv . If you want to eliminate this and have instead 2 separate formulas , use these ones:
APPENDNH(ai,a,i)=LAMBDA(ai,a,i,LET(k,AREAS(a),j,MAX(i,1),IF(j=k+1,ai,APPENDNH(APPEND2H(ai,INDEX(a,,,j),),a,j+1))))
APPENDNV(ai,a,i)=LAMBDA(ai,a,i,LET(k,AREAS(a),j,MAX(i,1),IF(j=k+1,ai,APPENDNV(APPEND2V(ai,INDEX(a,,,j),),a,j+1)))) also recursive ofcourse.
Excel Formula:
=LAMBDA(ai,a,hv,i,
    LET(k,AREAS(a),
       x,OR(hv={"h","v"}),j,MAX(i,1),
       IF(j=k+1,IF(x,ai,"''h''or''v''only"),APPENDNHV(IF(hv="h",APPEND2H(ai,INDEX(a,,,j),),APPEND2V(ai,INDEX(a,,,j),)),a,hv,j+1))
   )
)
