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: VBA_summaryMFX.m
    path of file: ./repos/PsPM/src/ext/VBA
    
    the code of the file until where you have to start completion: function str = VBA_summaryMFX(out)
% writes a summary string from output of VBA_MFX model inversion
% function str = VBA_summaryMFX(out)
% IN:
%   - out: the 'out' structure of VBA_MFX inversion routine
% OUT:
%   - str: a cell array of strings, which summarize the VBA inversion

str{1} = sprintf(['Date: ',datestr(out.date)]);
s0 = ['VB converged in ',num2str(out.it),' iterations'];
try
    if floor(out.dt./60) == 0
