.TH spec G "April 1993" "Scilab Group" "Scilab Function"
.so ../sci.an 
.SH NAME
spec - eigenvalues
.SH CALLING SEQUENCE
.nf
evals=spec(A)
.fi
.SH PARAMETERS
.TP
A 
: real or complex square matrix
.TP
evals
: real or complex vector
.SH DESCRIPTION
.Vb evals=spec(A)
returns in  vector \fVevals\fR the eigenvalues of \fVA\fR.
.LP
Eigenvectors are obtained by \fVbdiag\fR.
.SH EXAMPLE
.nf
A=diag([1,2,3]);X=rand(3,3);A=inv(X)*A*X;
spec(A)
//
x=poly(0,'x');
pol=det(x*eye-A)
roots(pol)
//
[Ab,X,bs]=bdiag(A);
Ab
clean(inv(X)*A*X)
