function tstY = svroutput(trnX,tstX,ker,kerOptions,beta,bias)
%SVRMSE Calculate SVR Output
%
%  Usage: tstY = svroutput(trnX,tstX,ker,kerOptions,beta,bias)
%
%  Parameters: trnX       - Training inputs
%              tstX       - Test inputs
%              ker        - kernel function
%              kerOptions - kernel options
%              beta       - Difference of Lagrange Multipliers
%              bias       - bias
%              comp       - sparse components
