MATLAB: Rename a variable

rename a variable

in my workspace i have an array that is named 'data' and I have a name field with some filename = 'filename'

I would like to rename the array called data to the name that is stored in the filename name variable.

simply doing filename = data; renames data to filename not the actual name that filename holds.

Let me see if I interpret the question correctly: you have

filename = 'bob';
data = [1,2,3];

And you want to rename data to bob (the contents of filename)?

Firstly, be careful doing things like this. It makes it very hard to track names. But, if you must...

str = [filename,'= data;'];
eval(str);

Why not store them in a struct array? If all mat files have the same fields that should work very well.

MATLAB: Use Value of String Array to name a variable

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{:});
