hi

in matlab POLYNOMIAL EIGENVALUE PROBLEM solve whit polyeig code 

why maple can't solve  ?!?

[A]+[B] N+[C] N^(2)+[D] N^(3)+...N^(8)

[A],[B],[C],[D],... is known 8*8 matrix ;

how to find Eigenvalues and Eigenvectors and N?

eig([A],[B],[C],[D],...) ?!?!?

4200000*(diff(T(x, t), t))-0.1e-2*(diff(T(x, t), x))^2-0.1e-2*(diff(T(x, t), x, x))*T(x, t)-.445*(diff(T(x, t), x, x))-158780+4200*T(x, t)-50000/(exp(x))^200 = 0

with boundry conditions:

u[0](0.3e-1, t) = 37

hi,

how to solve Ax=0 ?

A is 8*8 Matrix and det(A)=0
how to find x (x1,x2,...,x8) ? 

 

thx;

aryan.
