clc
if vs=="AC"
    c=0.8;
    iv=acvi;
else
    c=1;
    iv=dcvi;
end
for k =1:numel(lo);
    lva=lo(k)./c;
    lvah=lva.*t;
    ll=lo(k)./iv;
end
slo=sum(lo);

I have a sample script which i input to the above as a "function" ('AC',[25 45 65 78 120 65],8, 415,24) ie a string, vector and doubles now when i sum the input vector there is no drama for the initial vector however when i sum the other vectors, (lva,lvah,ll) i get the correct values after elementwise manipulation but cannot sum them i only the output of the last known value. Any ideas? I'm sure the solution is quite simple but its racking my brain. :(

Thanks,

Frank

Replace

vs=="AC"

with

strcmp(vs,'AC')

KSSV your comment is legitimate but not the answer i was looking for i want to sum the elementwise vectors?

Hi

You can refer the below code which can be used to find the sum of the elements which you are doing. Hope it will help!

function [slva, slvah, sll, slo] = compute(vs,lo, acvi, dcvi, t)
    if strcmp(vs, 'AC')
        c = 0.8;
        iv = acvi;
    else
        c = 1;
        iv = dcvi;
    end
    lva = lo/c;
    lvah = lva * t;
    ll = lo/iv;
    
    slo = sum(lo);
    slva = sum(lva);
    slvah = sum(lvah);
    sll = sum(ll);
    
end
