Portfolio optimization - quad prog function

Hi,

I have a function mean_var_portopt1 (here attached). I am trying to call the function by writing:

targetreturn=0.07
% Determine the efficient portfolio weights given the target return.

[Weff]= mean_var_portopt1(targetreturn, Rets);

Rets is a 3740x5 matrix of asset returns. As a result, I should get a 5-element column vector with asset weights but instead I get a 5x5 matrix, why is that?

Thanks!

When I run your code, I do get a 5x1 columns vector.

You do? how come? ...

There's no apparent reason that I should not. My guess is that you did not actually input targetreturn=0.07, but rather some non-scalar value.
