error in load function

i extracted this code from a pdf given at the bottom.

I gave my input and output files for training.

i am able to run all other codes except the last one.

I got error in load('run_log_2') and i do not know what it means.

%% network output
clear;
close all;
load('run_log_2');
nn=4;
ptrain=p(opt(nn).trainInd);
ttrain=t(:,tropt(nn).trainInd);
esttrain=sim(netopt{nn},ptrain);
ptest=p(:,tropt(nn).testInd);
ttest=t(:,tropt(nn).testInd);
esttest=sim(netopt{nn},ptest);
pval=p(:,tropt(nn).valInd);
tval=t(:,tropt(nn).valInd);
estval=sim(netopt{nn},pval);
estwhole=sim(netopt{nn},p);
figure;
plot(ttrain,esttrain,'.b');
figure;
plot(tval,estval,'.g');
figure;
plot(ttest,estttest,'.r');
figure;
plot(t,estwhole,'.k');
figure;
plotregression(ttrain,esttrain,'Train',tval,estval,'Validation',ttest,esttest,'Test',t,estwhole,'Whole Data');

Please help me!!

Do you have a file named "run_log_2" in the same folder that the matlab script runs from? What does your error message say?

[Ameer Hamza]

Since you are copying code from the pdf file, most probably, you don't have the file run_log_2. Your best bet is to request the author of the paper to provide you the file.
