+% SET_PARAMS Set the parameters (fields) for a gaussian_CPD object
+% CPD = set_params(CPD, name/value pairs)
+%
+% The following optional arguments can be specified in the form of name/value pairs:
+%
+% mean       - mu(:,i) is the mean given Q=i
+% cov        - Sigma(:,:,i) is the covariance given Q=i 
+% weights    - W(:,:,i) is the regression matrix given Q=i 
+% cov_type   - if 'diag', Sigma(:,:,i) is diagonal 
+% tied_cov   - if 1, we constrain Sigma(:,:,i) to be the same for all i
+% clamp_mean - if 1, we do not adjust mu(:,i) during learning 
+% clamp_cov  - if 1, we do not adjust Sigma(:,:,i) during learning 
+% clamp_weights - if 1, we do not adjust W(:,:,i) during learning
+% clamp      - if 1, we do not adjust any params
+% cov_prior_weight - weight given to I prior for estimating Sigma
+% cov_prior_entropic - if 1, we also use an entropic prior for Sigma [0]
+%
+% e.g., CPD = set_params(CPD, 'mean', [0;0])
