Hi Iman,
The problem is with the syntax you have used.
If you use the results structure ‘results=runpf(mpc)’ you cannot extract the
losses results using ‘loss=get_losses(MVAbase, bus, branch)’ because it is only
compatible with the previous versions of MATPOWER. To return results as
individual output arguments, use this
define_constants;
mpc = loadcase('case14');
[PLOSS,MVAbase, bus, gen, branch, success, et]=runpf(mpc);
loss=get_losses(MVAbase, bus, branch)
You can go through the MATPOWER M- file ‘ runpf.m’ it will help a lot.

Dear Alvaro,
Thank you for your help.I added function loss = get_losses(baseMVA, bus,
branch) based on the presented scripts.My problem is that I don't know how to
call it in my program.
for example I called this function as :
define_constants;
mpc = loadcase('case14');
results=runpf(mpc);
loss=get_losses(baseMVA, bus, branch);
I get the error message .
In the next step I thought that I have not passed the values
(baseMVA,bus,branch) to the function so I corrected it as :
loss=get_losses(100, 1, 1);
but again a new error as follows:
??? Error: File: get_losses.m Line: 47 Column: 72
Expression or statement is incorrect--possibly unbalanced (, {, or [.
I suspect that my function calling is wrong.So for example what should I write
if I want to say the get the losses in branch 1-2?
Thank you Alvaro and everyone else.
Best wishes
Iman
