Assigning a variable according to file name..

I want the variable to be changed according to the file name.. Like;

Simulation File 1 Track 2

Simulation File 1 Track 4

Simulation File 1 Track 6

.

.

.

I want those track values assigned in a formula and get the value as the loop continues taking the track value like 2-4-6. Thank you all

"I want the variable to be changed according to the file name.."

That would be about the worst approach to importing data.

Putting meta-data into variable names is a sign that you are doing something wrong.

Meta-data is data and belongs in variables, not forced into variable names. Badly designed data (with meta-data in the variable names) makes accessing the data slow, complex, inefficient, obfuscated, buggy, and difficult to debug:

The MATLAB documentation shows examples which use simple and efficient indexing to store imported file data:

https://www.mathworks.com/help/matlab/import_export/process-a-sequence-of-files.html

Is there a particular reason why you cannot use simple, neat, efficient indexing and a cell array? (or a table, struct, etc)

Stephen, I appriciate your helps indeed.. That's because I am absolutely rookie about coding. I almost know nothing I can say.. Process just came in a way like this and I have to get that going : (

OK.. I took Stephen's advice and decided to do this in a different way.. From 1 to 480, I want to multiply

1st row with 0

2nd with 10

3rd with 2

4th with 4

5th with 6

6th with 8

and then

7th with 0 again

8th with 10 again.. son on ! Every 6 turns it should repeat this till 1 to 480

You need not to change the variable as based on filename..you can initialize an array/ matrix and save the variables into this.

Option 1: If size is always same

n = 10 ;   % number of files 
iwant = zeros(3,3,n) ;   %
for i = 1:n
    iwant(:,:,i) = rand(3) ;   % save data here 
end

Otion 2: If size varies

n = 10 ;
iwant = cell(n,1) ;
for i = 1:n
    m = randperm(100,1) ;
iwant{i} = rand(m) ;
end

Example:

Track = 2;
File = 2;
Filename = {};
for j=1:(File)
    for i = 1:(Track)
        Filename{end+1} = ['SimulationFile' num2str(j) , ' Track' num2str(i)];
    end
end
