Having a matrix say 'A' whoose content is taken as variable for a P(x), which is a 3rd Degree polynomial, resulting in a Matrix 'Ax'. What operation should be done between P(x) and 'Ax' to get back 'A' ?
sample code is …
A=[0:0.01:1];Ax = p1*A.^3 + p2*A.^2 + p3*A + p4; % p1 to p4 are coefficients of polynomials
How can 'A' be recovered from 'Ax' using P(x) ?
