How to attach multiple matrices to a single matrix?

There are A, B, C, and D matrices of 100x1 size.
I would like to combine this data into a matrix of 400x1 size.
However, the conditions must be followed by 5x1 of each matrix.
A = [1,2,3,4,5,6,7,8,9,10....]
B = [a,b,c,d,e,f,g,h,i,j...]
C = [11,22,33,44,55,66,77,88,99...]
D = [A,B,C,D,E,F,G,H,I,J...]
Assuming that it's like this,
F = [1,2,3,4,5,a,b,c,d,e,11,22,33,44,55,A,B,C,D,E,...]
I'm going to make these results.
The method I tried was:
Inside the for loop
Use the fseek function to add 'offset=0' first and then 'offset=5'.
I saved it using the spread function.
I got the result I wanted.
I'm wondering what else you can do.

The code below will keep repeating the values form each array 5 by 5, i.e. it won't use only the first 5 values of each array.
In the example below I used 1x15 arrays (I don't know what's after "z" in B and C). Just replace your array and it should work
clear,clc
A = 1:15
A = 1×15
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
B = {'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o'}
B = 1×15 cell array
{'a'} {'b'} {'c'} {'d'} {'e'} {'f'} {'g'} {'h'} {'i'} {'j'} {'k'} {'l'} {'m'} {'n'} {'o'}
C = 11:11:165
C = 1×15
11 22 33 44 55 66 77 88 99 110 121 132 143 154 165
D = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O'}
D = 1×15 cell array
{'A'} {'B'} {'C'} {'D'} {'E'} {'F'} {'G'} {'H'} {'I'} {'J'} {'K'} {'L'} {'M'} {'N'} {'O'}
A = reshape(A,5,[]);
B = reshape(B,5,[]);
C = reshape(C,5,[]);
D = reshape(D,5,[]);
OUT = [num2cell(A);B;num2cell(C);D];
OUT = OUT(:)'
OUT = 1×60 cell array
{[1]} {[2]} {[3]} {[4]} {[5]} {'a'} {'b'} {'c'} {'d'} {'e'} {[11]} {[22]} {[33]} {[44]} {[55]} {'A'} {'B'} {'C'} {'D'} {'E'} {[6]} {[7]} {[8]} {[9]} {[10]} {'f'} {'g'} {'h'} {'i'} {'j'} {[66]} {[77]} {[88]} {[99]} {[110]} {'F'} {'G'} {'H'} {'I'} {'J'} {[11]} {[12]} {[13]} {[14]} {[15]} {'k'} {'l'} {'m'} {'n'} {'o'} {[121]} {[132]} {[143]} {[154]} {[165]} {'K'} {'L'} {'M'} {'N'} {'O'}
