Help with matrix concatenation!

Hello! I need some help creating a program. I need to write a program who recieves as arguments the matrix(same order): L,U,Q and R,Q are invertible matrix. The program returns the resultated matrix by vertically concatenation of 2 matrixes. The first one it's built by concatenation-horizontally of the matrix L,U,Q and R, and the second one by concatenation-horizontally of matrix L * U , U + R , L(transpose)and Q(at -1) +R . The program returns vid matrix if the conditions are not respected.

This totally beats my 1 week(training) in MatLab!

Thank you very much!

To concatenate horizontally:

wideMatrix = [A,B,C,D]; % All have same # of rows.

To concatenate vertically:

tallMatrix = [A;B;C;D]; % All have same # of columns.
