How do I align the matrices of variable sizes using the Dynamic time warping algorithm?

Hello there,
I have a problem where there are three matrices X,Y,Z of variable sizes and I would like to align them all to the same uniform size, however, making sure that the information is not lost from the data. While browsing I came across a method called Dynamic time warping, however, I couldn't do much with the available examples. Can someone help me with this, attached is the spreadsheet with data.
Thanks in advance.

Have you tried predetermining the size of the matrices before assigning values?
ex:
x = zeros(5); y = zeros(5); z = zeros(5);
x(:,1) = [1;1;1;1;1]; y(:,3) = [1;1;1;1;1]; z(:,5) = [1;1;1;1;1];
x, y, z
You can also insert null values to make matrices equivalent sizes.
