I want to calculate the modulo multiplicative inverse of a Polynomial. Here, A=(3 + 2*X^2 -3*X^4 + X^6) and P=7 to satisfy the condition X*A = 1 (modulo P), where X is the polynomial inverse. I want programming codes or function to solve this problem. How it can be solved in MATLAB through function.
