function [mean,stdev] = stats(vals)
%#codegen
%calculates the statistical mean 
%and s.d for the values in vals
len = length(vals);
mean = avg(vals,len);
stdev = sqrt(sum(((vals-avg(vals,len)).^2))/len);
coder.extrinsic('plot');
plot(vals,'-+');
function mean = avg(array,size)
mean = sum(array)/size;

Have you tried copying your model to another folder?

You should move your models and codes to a folder which is not the installation folder of MATLAB. Your desktop or 'my documents' should work.

Oh! thank you, I managed to change the directory and things worked just fine. The trick was to leave the default display windows of MATLAB so as to be able to change to the directories of origin easily. THank you though.
