SPIDER The Spider Objects
Mapping object A=MAP(H) returns a map object initialized with hyperparameters H. MAP is a general object for mapping data, it takes a supplied mapping function which can transform the given input data. The function can use four hyperparmeters p1,p2,p3,p4. Hyperparameters, and their defaults func='d.X=tanh((d.X+a.p1)*a.p2)' -- function we wish to use. This can be changed at will, it can access the object 'd' (data) and 'a' (mapping algorithm), e.g d.X, d.Y, a.p1, a.p2, etc. and usual matlab functions. It should store the new values in d.X. The default is a sigmoid mapping. p1=1,p2=0,p3=[],p4=[] -- user parameters
