3.2.4 Variables

After the (go) command, gmeteor stores the result of the computation into certain global variables, which you can access for further processing.

— Variable: *result*

The result of the filter optimization problem. This variable contains one of the symbols 'optimal, 'infeasible, or 'unbounded. If the filter was computed correctly, the value is 'optimal. Otherwise, either there is no solution ('infeasible) or there are too many solutions ('unbounded).

— Variable: *coefficients*

A Scheme vector containing the filter coefficients.

— Variable: *y*

The final value of the deviation parameter y.
