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: min.m
    path of file: ./repos/chebfun/@separableApprox
    
    the code of the file until where you have to start completion: function g = min( f, g, dim )
%MIN   Minimum value of a SEPARABLEAPPROX in one direction.
%   MIN(f) returns a chebfun representing the minimum of the SEPARABLEAPPROX along the
%   y direction, i.e, MIN(f) = @(x) max( f ( x, : ) )
%

    
function g = min( f, g, dim )
%MIN   Minimum value of a SEPARABLEAPPROX in one direction.
%   MIN(f) returns a chebfun representing the minimum of the SEPARABLEAPPROX along the
%   y direction, i.e, MIN(f) = @(x) max( f ( x, : ) )
%
%   MIN(f, [], dim) returns a CHEBFUN representing the minimum of f along the
%   DIM direction. If DIM = 1 is along the y-direction and DIM = 2 is along the
%   x-direction.
%
%   WARNING: This function is not always accurate to the expected precision.
% 
%   For the global minimum use MIN2.
