build a polynomial matrix from its coefficients
[P]=inv_coeff(C,[,d,[name])
a big matrix of the coefficients
a polynomial matrix degree. The optional parameter with default value d=-1+size(C,'c')/size(C,'r')
a string giving the polynomial variable name (default value 'x'
).
P=inv_coeff(Mp,k)
, when k
is compatible with Mp
size, returns a polynomial matrix of degree k
. C=[C0,C1,...,Ck]
and
P= C0 + C1*x +... +Ck*x^k
.
