matrix.

***** define a matrix with the compute command****.

      ***** A is a 2 X 2 matrix********.
compute A={3,2;4,0}.

      ***** B is a 2 X 5 matrix*********.
compute B={1,3,0,5,7;2,4,3,3,3}.

      ***** C is a 2 X 2 matrix*********.
compute C={0,8;9,1}.

***** transpose B******.
compute Btrans=transpos(B).

****** Add *****.
compute AplusC=A+C.

***** multiply****.
compute AB=A*B.

***** inverse*****.
compute inverseA=inv(A).

***** determinant ***.
compute detA=det(A).

*******print the results ********.
print A /title "Matrix A".
print B /title "Matrix B".
print Btrans /title "B transpose".
print AplusC /title "A + B".
print AB /title "AB".
print inverseA /title "A inverse".
print detA /title "Det A".

end matrix.
