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_getLaplace.m
    path of file: ./repos/VBA-toolbox
    
    the code of the file until where you have to start completion: function [muy,Vy,iVp] = VBA_getLaplace(u,f_fname,g_fname,dim,options,checkVar,reduceVy)
% returns the Laplace approximation to the prior predictive density
% function [muy,Vy,iVp] = VBA_getLaplace(u,f_fname,g_fname,dim,options)
% IN:

    
function [muy,Vy,iVp] = VBA_getLaplace(u,f_fname,g_fname,dim,options,checkVar,reduceVy)
% returns the Laplace approximation to the prior predictive density
% function [muy,Vy,iVp] = VBA_getLaplace(u,f_fname,g_fname,dim,options)
% IN:
%   - u: experimentally controlled input (design)
%   - f_fname: the evolution function
%   - g_fname: the observation function
%   - dim: the model dimension structure
%   - options: the options structure
%   - checkVar: flag for eyeballing the quality of the covariance matrix
% OUT:
%   - muy: the 1st-order moment of the prior predictive density.
%   - Vy: the second-order moment of the prior predictive density.
%   - iVp: the predicted posterior precision matrix of the model parameters
