please help

a)Write a MATLAB function (not just a generic m-file, but a function ) that allows you to input E1, E2, G12, and V12 and which returns [9] and [S] as output. Use it to determine the 2D stiffness and compliance matrixes ( [Q] and [S] matrixes, respectively) for the T300/934, AS/3501 and P- 100/ERL1962 carbon/epoxy materials using properties from Gibson Table 2.2.
