Programming in Matlab. i need net1, net2 and net3 constructed. but i have only net replaced 3 times. the variable net might be unused is the warning. please help

for sheetno=1:3
      dn1='net'  ;
  dn2=num2str(sheetno);
    net=[dn1 dn2];
net=fitnet(10);
end

i have to make 3 net inside the loop so that i can have 3 nets to be saved for future use with load command. sheetno is the running variable attached to net so that i can have net1, net2 and net3 after the completion of the loop

Is there any variable declaration like static which can be made non-static later in the program?

"Is there any variable declaration like static which can be made non-static later in the program?"

No. The only variable declarations are global and persistent

In your situation I would save the values inside a structure using dynamic field names. Then save() the structure using the -struct option.

[Walter Roberson]

for sheetno=1:3
  thisfield = sprintf('net%d', sheetno);
  mynets.(thisfield) = fitnet(10);
end

save('mynets.mat', '-struct', 'mynets');

Now mynets.mat will contain variables net1, net2, net3

thank you Walter R. i was able to make three networks inside the loop. but when i call using "load net1" it says error. unable to read file. itried with "load mynets.net3" also returened error. please tell me how to use the created networks inside the loop.

load('mynets', 'net1')

thank you very much walter R.

[Dhandapani.S]

inpsam=input('input sample number','s');

openn=strcat('net',inpsam);

load('mynets',openn);

output=openn(featureset1');

in the above code, openn variable has the value 'net4' when the input to inpsam is 4. but the error in the last line of code is "Subscript indices must either be real positive integers or logicals."

i am able to create multiple nets and able to save with different index nummbers suffixed. when loading the trained net, i get error. please help

[Walter Roberson]

inpsam=input('input sample number','s');
openn=strcat('net',inpsam);
filedata = load('mynets',openn);
saved_net = filedata.(openn);

output = saved_net(featureset1');

Thank You very much Walter.
