Hi,
I have a code which reads data from all the csv files and converts them to wav files with the same name as the csv file in a different folder. What I want to do now is read all the csv files and save the time domain plots for each one of them with the same name as the csv file and in a different folder. How can I do that? Thanks.
clearvars
indir = '.'; %current directory
outdir = 'C:\Users\gagan\Downloads\testing_lab\Stage-1 testing\plots'; %where to write the results
files = dir( fullfile(indir, '*.csv'));
for file = files'
inname = fullfile(file.folder, file.name);
n = readmatrix(inname);
m = rescale(n, -1, 1, 'InputMin',2301,'InputMax',3642)+0.527;
[filepath,name,ext] = fileparts(inname);
outname = fullfile(outdir, name + ".wav");
%audiowrite(outname, m_filtered, 40000, 'BitsPerSample', 16);
%instead of audiowrite, make plots here and save the plots.
end

plot(m) ; % use your variable in the plot
