%SETPRIOR Reset class prior probabilities of dataset%%   A = SETPRIOR(A,PROB,LABLIST)%% INPUT%   A        Dataset%   PROB     Prior probabilities to be set%   LABLIST  Label list (optional)%% OUTPUT%   A        Updated dataset%% DESCRIPTION% Resets the class prior probabilities of the dataset A to PROB. PROB should% be a vector of the length equal to the number of classes in A. In LABLIST,% the corresponding class labels may be supplied. LABLIST may have only% class names of the existing classes in A. Reset class names first by % SETLABLIST if necessary.%% If LABLIST is not given, the order defined by the existing LABLIST for A% (determined by [NLAB,LABLIST] = renumlab(LABELS)) is used.%% PROB = 0 makes all C classes equally probable: 1/C.% PROB = [] is interpreted as using the existing class frequencies in A as% prior probabilities. Note that these prior probabilities change, if the% number of elements in A is changed.
