I have three sudio files and each have the same variables('measuredSystem_L','measuredSystem_R').I want to store the values of the variables in same matrix without the previous value being overwritten.I will state the situation.

I have written a code for this script but the previous values are getting overwritten.How can I keep such a script where all the values of the same variables are stored respective to the audiofile. My code:

matfiles=dir('*audiointerface*.mat');
N=length(matfiles);
filenames=cell(N,1);
for i=1:N 
filenames{i}=matfiles.name; data=load(matfiles(i).name);
end

Use a cell array and indexing:

data = cell(N,1);
for k = 1:N
    data{k} = load(matfiles(k).name);
end

在 MATLAB Online 中打开

matfiles = dir('*audiointerface*.mat');
N = numel(matfiles);
C = cell(N,2);
for k = 1:N
    S = load(matfiles(k).name);
    C{k,1} = S.measuredSystem_L;
    C{k,2} = S.measuredSystem_R;
end

I would now try to plot the values stored in cell C{k,1} and C{k,2} in frequency domain using fft function.But I am not sure how to plot a value in a cell to that into frequency domain.My main goal is to compare ALL the values of C(k,1) in frequency domain and compare them

matfiles = dir('*audiointerface*.mat'); N = numel(matfiles); C = cell(N,2); for k = 1:N S = load(matfiles(k).name); C{k,1}=matfiles(k).name C{k,2} = S.measuredSystem_L; C{k,3} = S.measuredSystem_R; end This gave me complete information of the variables and also which file it belonged to
