You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: loadSyntheticProblem.m
    path of file: ./repos/lrslibrary/algorithms/rpca/SPGL1
    
    the code of the file until where you have to start completion: function [Y,L,S,params] = loadSyntheticProblem(varargin)
% [Y,L,S,params] = loadSyntheticProblem(problemName, referenceSolutionDirectory)
%
% Returns parameters and solution for the following problems
%   (parameters are tuned so that each problem has the
%    the same true solution (L,S) )
% Or, call this with no input arguments to set the path...
%
% "Lag": min   lambdaL*||L||_* + lambdaS*||S||_1 + .5||L+S-Y||_F^2
% 
% "Sum": min   ||L||_* + lambdaSum*||S||_1 
%        subject to ||L+S-Y||_F <= epsilon
%
% "Max": min   max( ||L||_* , l
    
function varargout = my_rng(varargin)
%MY_RNG Control the random number generator used by RAND, RANDI, and RANDN (SRB version)
%   MY_RNG(SD) seeds the random number generator using the non-negative
%   integer SD so that RAND, RANDI, and RANDN produce a predictable
%   sequence of numbers.
