    respected sir,

    I am in need of matlab program for finding
    "MULTIPLICATIVE INVERSE(GF(2^8)) for the hexadecimal no. or
    binary(8-bits)no.



    (multiplicative inverse)

    Do you have access to the MathWorks Communications Toolbox? It should
    have the answer to this question among its Galois Field operations, in
    particular with its division operation. Their website at

    http://www.mathworks.com/access/helpdesk/help/toolbox/comm/

    has examples of finding multiplicative inverses. What prime polynomial
    are you using?
