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;
