Vectorize for loop with sum

[Rick T]

How can I vectorize this for loop?

    t_rebuilt=linspace(0,1,length(inner_freq));

    for ii=1:1:length(inner_freq);ii=ii+1; 

        

        aa_sig_rebuilt=inner_freq(ii,2)*cos(2*pi*t_rebuilt*inner_freq(ii,1)+inner_freq(ii,3));

        aa_sig_combined=aa_sig_combined+aa_sig_rebuilt;

        

    end;

I tried replacing it with the lines below to see if it worked but I just get a straight line when I plot it

aa_sig_rebuilt=inner_freq(ii,2).*cos(2*pi*t_rebuilt*inner_freq(ii,1)+inner_freq(ii,3));

and I also tried

aa_sig_rebuilt = sum(inner_freq(:,2).*cos(2*pi*t_rebuilt*inner_freq(:,1)+inner_freq(:,3)));
