How can I make this type of array.

How can I copy the same array like the image ( It only adds another zero to the array) and combine them to make 2 rows?

yk=[0.0000;0.01953;0.07567;0.14890;0.22945;0.31001;0.39300;0.47111;
0.54922;0.62245;0.69324;0.76159;0.82750;0.89096;0.95199;1.00812;1.06427;1.11553;1.16435;1.21561;1.26199] 

 uk=ones(20,1)

Should be easy, but I don't quite understand what you want as output.

yk is a 21x1 array. uk is a 20x1 array.

Do you want your final array to be 21x4, or 20x4, or something else?

horzcat(yk,[0;yk(1:end-1)])

ans =

                   0                   0
   0.019530000000000                   0
   0.075670000000000   0.019530000000000
   0.148900000000000   0.075670000000000
   0.229450000000000   0.148900000000000

Pending an answer to the question in my comment, here is my best current guess as to what you want:

output = [yk, [0; yk(1:end-1)] uk [0; uk(1:end-1)]];

where I actually define

uk = ones(21,1);

instead of your 20x1 array.
