 %   Function gets as input
 %       b - measurement vector 
 %       A - dictionary 
-%       param - structure containing additional parameters
+%       param - structure containing additional parameters. These are:
+%           - initcoeff   Initial guess for the coefficients
+%                         (optional)
+%           - to          1/(step size). It is larger than spectral norm
+%                         of dictionary A (default is 0.1+(svds(A,1))^2)
+%           - lambda      Lagrangian multiplier. Regulates shrinkage
+%                         (default is 0.4)
+%           - iternum     Inner-loop maximum iteration number 
+%                         (default is 1000)
+%           - epsilon     Stopping criterion for iterative softthresholding
+%                         (default is 1e-7)
+%           - map         Debiasing. 0 = No, 1 = Yes (default is 0)
