+function smoother2histval(file, period, invars, outvars)
+% This function takes values from oo_.SmoothedVariables and copies them into
+% M_.histval.
+% 
+% INPUTS
+%    file:        An optional *_results MAT file created by Dynare.
+%                 If present, oo_.SmoothedVariables is read from there.
+%                 Otherwise, it is read from the global workspace.
+%    period:      An optional period number to use as the starting point
+%                 for subsequent simulations. It should be between 1 and
+%                 the number of observations that were used to produce the
+%                 smoothed values. If absent, the last observation is used.
+%    invars:      An optional cell array listing variables to read in
+%                 oo_.SmoothedVariables. If absent, all the endogenous
+%                 variables of the current model are used (from M_.endo_names)
+%    outvars:     An optional cell array listing variables to be written in
+%                 M_.histval. This cell must be of same length than invars,
+%                 and there is a mapping between the input variable at the
+%                 i-th position in invars, and the output variable at the
+%                 i-th position in outvars. If absent, then taken as equal
+%                 to invars.
