balance (Matlab function) Diagonal scaling to improve eigenvalue accuracy

## Matlab/Scilab equivalent

Matlab | Scilab
    balance
    balanc

## Particular cases

There is no equivalent for B=balance(A) in Scilab, balanc function does not work with only one output value.

When used with two outputs, these functions return value in inverse order.

## Examples

Matlab | Scilab
    [T,Ab] = balance(A)
    [Ab,T] = balanc(A)
