how to create a table in matlab to list my results in without the need to run the program each time to get the results and plot

Asked by mary on 27 Dec 2012

i ran the same program twice in two cases to get the value of SNR & BER and i got two list of values for each .. how can i apply it in a runnable table plz?

Maybe you can create an M x N matrix to store the result of M values of SNR for each of N experiments. So, for example, you could pre-allocate:

   M = size(snr,2);
   N = ...
   errorCount = zeros(M,N);
   ...
   ...
   ber = errorCount/I;
   ...
   ...

HTH.

I want to recall M different values of SNR and M different values for BER from two different programs. I want to use them to drow two curves

So that means N = 2, and you can use the method that I proposed in my answer above. Does that make sense to you? If not, what specifically is not clear?

What is a "runnable table"? What does "apply" mean? If you want to save variables from a run of your program, you can use the save() function. If you need to recall them into another run of your program, you can use the load() function. If you want to have a table, you can use the uitable() function or GUIDE to create a grid/table. Beyond that, I have no more guesses about what you mean.

I don't have randsrc() so I can't run your program. You can use uitable() to create a table, then do something like

set(handleToYourTable, 'Data', yourMatrix);

I want to recall M values of SNR and M values of BER from two different programs so this didn't work

Pass them via the argument list, or via .mat files.
