Extracting data from SimulationOutput from multiple simulations

Hi ,

I have done parallel simuation using parsim and singl eoutput file is generated. The Simulation Output object conatibns 8 runs of the same model ( Picture 1).

Now I want to extarct data of a specific signal from all the 8 runs in into one variable.

Currently I am using something like this,. It i sworking though , but is there any better way to do it as the numebr of signal to be processed is very large.

( TP_rms is a custom function )

No_iter= 8;

PCC_V_All=[];

for k_index=1:No_iter

PCC_V = TP_rms(get(out(1, k_index).logsout,'PCC_Vabc').Values.Data);

PCC_V_All=[PCC_V_All, PCC_V];

end

PCC-V signal is 1200x3. and the output PCC_V_All would be 1200X24.

Please suggest a better way to do this.

Answer 1

[Paul]

signalname = 'PCC_Vabc';
PCC_V_ALL = cell2mat(arrayfun(@(out) TP_rms(get(out.logsout,signalname).Values.Data),out,'UniformOutput',false));

There would be alternatives to fucntionalize this with signalname as an input.

@Paul Exactly what I wanted. Thanks!!!

I have converted this to a function. Do you suggest any improvements?

function [MatVal]= Log2Mat_TPrms(signalname,out)

MatVal = cell2mat(arrayfun(@(out) TP_rms(get(out.logsout,signalname).Values.Data),out,'UniformOutput',false));

end

[Paul]

You could make the whole thing into one anonymous function if you want. Not sure that would be an improvement over an m-function.

Also, I should point out that the combination of arrayfun and cell2mat in my Answer might be slower than the for loop and horizontal concatenation in @madhan ravi's Answer. If speed matters, you should compare with your typical data sets. If speed isn't the deciding factor, go with whatever you like for whatever reasons you choose.

[madhan ravi]

Surely to be more fancier, you could write 'UniformOutput', false as 'un', 0.

[madhan ravi]

No_iter= 8;
PCC_V_All = cell(1, No_iter);
for k_index = 1 : No_iter
    PCC_V{k_index} = TP_rms(get(out(1, k_index).logsout,'PCC_Vabc').Values.Data);
end 
  PCC_V_ALL = [PCC{ : }]
