eig (Matlab function)

Matlab/Scilab equivalent

eig

spec ; bdiag

Particular cases

eig(A)

Scilab equivalent for eig(A) is spec(A). Scilab eigenvector matrix can differ from Matlab one.

eig(A,'nobalance')

There is no Scilab equivalent for "nobalance" option. See examples.

eig(A,B,flag)

There is no Scilab equivalent for flag.

Additional Remarks

If matrix B is nonsingular, the generalized eigenvalues can be computed as the eigenvalues of the matrix i.e. d=spec(B^-1*A).

If A is a real random square matrix, Scilab equivalent for the Matlab syntax [V,D] = eig(A,'balance') is [D,V] = bdiag(A+%i*0, 1/%eps). In this case D consists of complex 1x1 blocks.

Examples

d = eig(A,'balance')
[V,D] = eig(A,'balance')
[V,D] = eig(A,'balance')
d = eig(A,B)
d = eig(A,B)
d = eig(A,B)
[V,D] = eig(A,B)

d = spec(A)
[D,V]=bdiag(A)
[V,D] = spec(A)
[al,be] = spec(A,B); d = al./be;
d = spec(A,B)
d = spec(inv(B)*A)
[al,be,V] = spec(A,B); D = diag(al./be);
