Hello,

Here is the error that I am getting from a pre-written code. Where should I begin debugging from? I am new to matlab and do not understand if I should try to modify all of these scripts? Alternatively, which one of these statements should I start from? see error below:

Error in fast_oopsi/est_MAP (line 306)

C = C1; % update C

Error in fast_oopsi (line 166)

[n C posts(1)] = est_MAP(F,P);

Error in run_oopsi (line 95)

[fast.n fast.P fast.V]= fast_oopsi(F,V,P);

Error in PostProcess (line 558)

x = run_oopsi(processed_analysis(j).dF_cell(m,:));

It is a bit difficult to give any considerable hints without looking at your codes/scripts. Thus, could you post your codes so community people can see what you are doing and how come these errs have popped up?

You didn't give the actual error. You gave the lines where the errors occurred (which is good since most people don't give that) but you didn't give the actual reason it thought

C = C1;

was bad. You might use whos on a line before that.
