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: spm_mix_demo1d.m
    path of file: ./repos/bspm/thirdparty/spm12/toolbox/mixture
    
    the code of the file until where you have to start completion: function [vbmix logev mix] = spm_mix_demo1d (data, maxcomps, verbosity)

    
function [vbmix logev mix] = spm_mix_demo1d (data, maxcomps, verbosity)
% Demonstrate use of spm_mix on 1D data
% FORMAT [vbmix logev mixdata] = spm_mix_demo1d (data, maxcomps, plotfits)
%
% data      - either scalar number of clusters to simulate or your own data
% maxcomps  - maximum number of components in mixture model to consider
% verbosity - 0 = silent, 1 = basic output (with figures), 2 = full output
%
% vbmix     - cell array of fitted mixtures for all numbers of components
% logev     - log evidence for each number of components
% mix       - mix structure for simulated mixtures if scalar data given
