Pls tell me where is the error.
for i= 0.01:0.02:0.99
w1_temp= i;
w2_temp= 1-i;
Rp_temp= w1_temp*mean(R_2(:,1))+w2_temp*mean(R_2(:,2));
Sp_temp= sqrt((w1_temp^2)*var(R_2(:,1))+(w2_temp^2)*var(R_2(:,2))...
hold on
xlim([0 2]);
ylim([0 0.12]);

ii = 0.01:0.02:0.99;
w1_temp= ii;
w2_temp= 1-ii;
Rp_temp= w1_temp*mean(R_2(:,1))+w2_temp*mean(R_2(:,2));
Sp_temp= sqrt((w1_temp.^2)*var(R_2(:,1))+(w2_temp.^2)*var(R_2(:,2))...
xlim([0 2])
ylim([0 0.12])

Not able to run the posted code:
Unrecognized function or variable 'R_2'.
That aside, be absolutely certain that you have not created variables named ‘mean’, ‘sqrt’, ‘var’, ‘plot’. ‘xlim’,’ylim’ or ‘C’, since creating those variables would throw the (unposted object) error.
Cannot go further without more information.
