% MAT2JSON Writes a JSON file
%
% mat2json(mat,filename)
%
% Inputs:
% mat: Matlab cell array whose entries are Matlab structures containing the
% value for each JSON field
% filename: JSON filename (.json extension)
%
% Note: using JSON2MAT followed by MAT2JSON will generally not lead back to
% the original JSON file due to the loss of digits beyond double precision
% and to the handling of trailing zeros.
