I have 2 separate arrays that I'm trying to concatenate.
ND is a 2x6 double array as follows;
ND = 58560 NaN 58561 -1100 -5100 4100
58570 Nan 59571 -1200 -5200 4200
OD is a 3x4 double array as follows;
OD = 58564 1 58563 11
58572 2 58573 21
58572 2 58573 22
The desired output array is shown below (3x 10 double array):
output = 58560 NaN 58561 -1100 -5100 4100 58564 1 58563 11
58570 NaN 59571 -1200 -5200 4200 58572 2 58573 21
58570 NaN 59571 -1200 -5200 4200 58572 2 58573 22
Since the dimensions do not allow for either vertical or horizontal concatenation, is there a technique I could use to achieve the desired output?

ND =[58560 nan 58561 -1100 -5100 4100;58570 nan 59571 -1200 -5200 4200]
OD =[58564 1 58563 11;58572 2 58573 21; 58572 2 58573 22]
n=size(ND,1);
m=size(OD,1);
ND(end:m,:)=repmat(ND(end,:),m-n+1,1)
out=[ND OD]

Azzi, thank you for looking at this. The answer you supplied works.
I do have a follow on question. In my original question, I supplied the sample arrays ND and OD, along with the desired output. In executing your answer I realized the sample matrices I supplied were too simplified. If the OD array is:
OD = 58564 1 58563 11
58564 1 58565 12
58572 2 58573 21
58572 2 58573 22
And the desired output is:
output = 58560 NaN 58561 -1100 -5100 4100 58564 1 58563 11
58560 NaN 58561 -1100 -5100 4100 58564 1 58565 12
58570 NaN 59571 -1200 -5200 4200 58572 2 58573 21
58570 NaN 59571 -1200 -5200 4200 58572 2 58573 22
How do I achieve the desired result when I can't use end as part of the repmat?

out = [ND(OD(:,2),:),OD]
