%DATASETM Fixed mapping for conversion to dataset
%
%   B = DATASETM(A)
%   B = A*DATASETM
%
% INPUT
%   A    Datafile or double array
%
% OUTPUT
%   B    DATASET
%
% DESCRIPTION
% This command is almost identical to B = PRDATASET(A), except that it
% supports the mapping type of construct: B = A*DATASETM. This may be
% especially useful to include the dataset conversion in the processing
% definitions of a datafile.
