I have a matrix of zeros

Z = zeros(11,20);

And I want to insert X into the first row:

X = [0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18]

And Y in the first column:

Y = [0; 0;1;2;3;4;5;6;7;8;9]

As well, how do I insert an element into a specific position of the Z matrix?

Say I want to put a predetermined value of Distance = 20 into the spot (6, 4) ( row 6, column 4) of matrix Z.

Thank you!

Z(1,:) = X;
Z(:,1) = Y;
Z(6,4) = 20;

Thank you!
