Error: structure has no member 'var'

Dynare help (legacy posts)

Dynare 4.1.1, RBC with stochastic proces:

i use this code:

for ii=1:10000 //10k simulations

stoch_simul(hp_filter=400, order = 1, periods = 157, drop = 100, nofunctions, nomoments, noprint); 

    
	D=oo_.var;
	for i=1:6 
	D(i)=D(i)/(sqrt(oo_.var(i,i))*sqrt(oo_.var(1,1)));
	corr_matrix(ii,i)=D(i);
end;

and there is a problem in processing model:

error: structure has no member ‘var’

Can you explain me what does it mean? what is wrong?

2

it means that structure oo_ doesn’t have a field named var

thanks for help. i’ve solved this problem, but now i have another one:

error ‘corr_matrix’ undefined

here is actual version of my code:

for i=1:8
D(i)=D(i)/(sqrt(oo_.var(i,i))*sqrt(oo_.var(1,1)));
corr_matrix(ii,i)=D(i);
end;
end;

output(ii,1) = std(y)/mean(y); 
output(ii,2) = std(c)/mean(c); 
output(ii,3) = std(i)/mean(i); 
output(ii,4) = std(l)/mean(l); 
output(ii,5) = std(k)/mean(k);

end;

disp('correlations: ');
corr_matrix(1,:)'
disp('deviations: ‘);
100*mean(output)’

anyone know how to solve it? :slight_smile:

You need to define corr_matrix before filling its elements, using something like:

corr_matrix = zeros(no_lines, no_cols);
