SPIDER The Spider Objects

TOY data for Regression problems

   A=toyreg(H) returns a toy regression object initialized with hyperparameters H. 
   This object can generate toy data for regression with
   N input dimensions and O output dimensions. 
   If "nonlinearity" is specified it uses a map object to calculate the
   Hyperparameters, and their defaults
    l=100          -- examples
    noiselevel     -- 0
    n=1            -- input dimension
    o=1            -- output dimension (possibly overriden by outpmap)
    nonlinear=0    -- if 1 uses "outpmap" to calculate Y=map(X)
    seed=-1       -- random seed used to generate it, if -1 do not
                     set seed
