help with matlab code-PLEASE

Dear Users,

New into MATLAB and I am trying to run a code but encounter the following error message:

Undefined function 'mvnrnd' for input arguments of type 'double'.

Error in apply_LSDV (line 161)
    smpi_rnd = mvnrnd(smpi,kron(omega,iQ)/nobs);

I have attached a portion (top portion) (please see below) of the code upto line 161 where the problem appears to be.

Please can you help?

Thanks,

Ozmando

% Set up Pi matrix (Hamilton 11.1.6)
piprime = zeros(K,K*p+dis*(q+1)); 
for i = 1:p;
    piprime(:,1+(i-1)*K:K*i) = phi(1+(i-1)*K:K*i,:);
end;
for i = 1:q+1;
    piprime(:,(K*p)+1+(i-1)*dis:(K*p)+i*dis) = theta(1+(i-1)*K:K*i,:);
end;    
pimat = piprime';
smpi = reshape(pimat,K*(K*p+dis*(q+1)),1);  % small pi (vector)

% **************************************************************
% Monte Carlo loop
mr_rnd = zeros((st+1)*dis,monte);
ce = zeros(dis,monte);  % Cumulative effects

for num = 1:monte;  % 'monte' times of iterations
    smpi_rnd = mvnrnd(smpi,kron(omega,iQ)/nobs);

That routine is part of the Stats Toolbox. Do you have that installed and licensed?

[Ozmando]

Yes I have it installed and licensed.

Thanks

To check: is the problem now solved, or does it continue?

What does

which -all mvnrnd

show ?

[Ozmando]

The problem continues; I am reinstalling matlab again as it has crashed few times now. Maybe that could be the problem.

Thanks for your kind advise.

best wishes,

Oz
