I have this code in a script and was trying to get the answer to come in a matrix form with all the coordsx in row1 and coord y in row 2 I keep getting answers for the x and y separately but need them in matrix form.

Thanks in advanc

Welcome, do improve the code with pre-allocation.

% Try this
% preallocate an array "coords"
coords=zeros(2,7);
for n=1:7
    coords(1,n)=-(xfactor*trav(n,4)+(dxdy(n,1)); % x-coordinates appear in row 1 of an array: "coords"
    coords(2,n)=-(yfactor*trav(n,4)+(dxdy(n,2)); % y-coordinates appear in row 2 of the same array: "coords"
end
