Undefined function or variable 'setdemorandstream'

I am working on a feed-forward neural network analysis using MATLAB. I am getting the following error:

Undefined function or variable 'setdemorandstream'.

Code is as follows:

setdemorandstream(391418381);

Any help in rectifying this error is appreciated.

Solution

  • These are the contents of the function, verbatim:

    function setdemorandstream(n)
%SETDEMORANDOMSTREAM Set default stream for reliable example results.
%
%  SETDEMORANDOMSTREAM(N) is less distracting in example code, but
%  equivalent to:
%
%    rs = RandStream('mcg16807','Seed',n);
%    RandStream.setGlobalStream(rs);

rs = RandStream('mcg16807','Seed',n);
RandStream.setGlobalStream(rs);

    Just save this as a file in your MATLAB path.

    However, your errors might not stop there - make sure you have the neural network toolbox installed.
