Use Value of String Array to name a variable

Hello,

I'm trying to combine results of multiple files into one struct.

Said struct should be named the following name:

result.[FileName1].Result1ofFile1
result.[FileName1].Result2ofFile1
result.[FileName2].Result1ofFile2
...
result.[FileNameX].ResultYofFileX

I save the file names in an String array. Thus

FileName(1) = "abc1"
FileName(2) = "abc2"
...

and so on.

Unfortunately I can't figure out how to make it work.

How can I use the String stored in an array as a variable name?

At the end it should look like this, without the need of typing in the abc-Names myself:

result.abc1.Result1ofFile1
result.abc2.Result1ofFile2

"Use Value of String Array to name a variable"

Your question shows that you actaully want to name a structure field, not a variable.

One answer to your question would be to use dynamic fieldnames:

But as Ameer Hamza wrote, a much better approach would be to store the filename as data in its own field.

First, I must say that this does not seem to be a good idea. It is better to store filenames as a separate field and create an array of the struct. For your case, something like this might be better.

result = struct('data', {}, 'filename', {});
result(1).data = Result1ofFile1;
result(1).filename = FileName(1);
result(2).data = Result1ofFile2;
result(2).filename = FileName(2);

For your current question, you can try something like this

FileName(1) = "abc1";
FileName(2) = "abc2";

C = cell(1, 2*numel(FileName));
C(1:2:end) = num2cell(FileName);
result = struct(C{:});
