Function not taking in input correctly from output of another function - help!

Hi all,

I've got two functions in my code. The output of the first function is a structure of this format:

    mystructure.nameofstruct = 'my_array';
    mystructure.valueofstruct = myarray;
    mystructure.outputofstruct = 1;

The output of mystructure.valueofstruct is

    mytitle001: 0

    mytitle002: 0.56

    ... etc up until

    mytitle040: 0.23

The second function takes in the output of the first one as input, however it seems to be doing it wrong, as the bit my structure.valueofstruct only has the last one "mytitle040: 0.23". I'm not quite sure why, as I would've thought it would take in the whole thing? Any ideas would be appreciated. Thanks.

Also, for more information, mystructure.valueofstruct is also another structure.

Please assign the output of the first function to a temporary variable, and then display fieldnames() of the valueofstruct field of that variable. Pass the temporary variable to the second function. Then, inside the second function, display fieldnames() of the valueofstruct field of the received input.

Hi,

fieldnames() in the first function returns:

    'mytitle001'
    'mytitle002'
     ...
    'mytitle040'

And fieldnames() in the second function of the input gives only this:

    'mytitle040'

Please show an extract of the code.

function mystructure = myfunction(inputs)

    for i = 1:40

      some calculations for number etc

        for j = 1:40
            my_new_name = oldname(16:27);
        end  

        myarray = struct(my_new_name,number);

    mystructure.nameofstruct = 'my_array';
    mystructure.valueofstruct = myarray;
    mystructure.outputofstruct = 1;

end

end

This is the first function. The second function is linked to this one, and takes in the mystructure structure as an input. I am starting to think that the for loop is complicating things there, and once the structure field is accessed outside it, it only gives the last title?

[Walter Roberson]

Why are you using a "for" loop to construct "my_new_name" as being the same thing each time?

Also, when you are using

mystructure.valueofstruct = myarray;

that is changing valueofstruct to be only what is in myarray, rather than changing valueofstruct to have an additional field. You should use

mystructure.valueofstruct.(mynewname) = number;

Thank you!
