Accessing cells of a cell array error

Hello everybody,

I want to modify the previous code of my stored data by accessing a cell array I've made. However, every time I want to access the second Element MATLAB states that my Cell array (datarpm) is a 1x1 Cell and there is no second cell to access. if I comment it out, MATLAB generates the cell array as a 1x19(which is expected) and I am able to access the second cell via the command window but not in the code section. Does anybody see my error?

Code below:

Drpm = 'C:\Users\Brendan\OneDrive\Masterarbeit_prädiktive_Stromregler\Modelle\01_Parameter\01_Ld\rpm';
files = dir(fullfile(Drpm, '*.csv'));
for i = 1:numel(files) 
    fnm = fullfile(Drpm,files(i).name); 
    datarpm{i} = readmatrix(fnm); 
    y = num2cell(datarpm, 1);
    thelp = y{1};
    t = thelp{1}(:, 1);
    x = datarpm{1};
   % x2 = datarpm{2}; %% This is where the problem occurs. Error: Index exceeds the number of array elements. Index must not exceed 1.
    rpm = x(:, 2);
end

at the first iteration of your loop ,you have only genrated datarpm{1} , datarpm{2} does not yet exist

this throw the error message

I wonder why you need to have access to datarpm{1} and datarpm{1} at each iteration step ?

Thank you!

I forgot about that. The datarpm{1} just comes from playing with the code. Works now
