%  Usage: tstY = sumsvroutput(trnX,tstX,ker,beta,bias)
%
%  Parameters: trnX   - Training inputs
%              tstX   - Test inputs
%              ker    - kernel function
%              beta   - Difference of Lagrange Multipliers
%              bias   - bias
%              comp   - sparse components
