How to save multiple polts with the source file name using loop?

How to save multiple polts with the source file name using loop?

Code

folder = "C:\Users\91743\OneDrive\Documents\MATLAB\MATLAB\Files"; % specify the path to the folder

%filepattern=fullfile(folder,'.csv');

files = dir(fullfile(folder, '*.mat')); % get a list of all .mat files in the folder

nFiles = numel(files); % number of files in the folder

for i = 1:nFiles

signal=fullfile(folder, files(i).name); % load the signal from the .mat file

%x = signal; % extract the signal from the .mat file

% signal1=signal(:,1);

D = load(signal); % ugh ugh ugh, that ugly prefix on those poor variable names!

D = cell2struct(struct2cell(D),regexprep(fieldnames(D),'^\w\d+_?',''),1); % much better.

files(i).data = D;

D=[files.data];

current_signal=D(i).DE_time;

%signal1=struct2array(signal);

%field_names=getfield(signal);

%current_signal=field_names{1};

%disp(current_signal);

%current_signal1=load(current_signal'.mat');

%current_signal1=

Fs=51200; %sampling frequency

T=1/Fs; %sampling period

L=length(current_signal); %Lenght of the signal

%t=((0:L-1)*T);

req=((0:L-1)*Fs/L);

xdft1 = fft(current_signal); %Compute FFT

xdft1 = 1/L*xdft1; %Normalize

xdft1(2:end-1) = 2*xdft1(2:end-1);

X_mag = abs(xdft1);

freq=((0:L-1)*Fs/L);

%X = fft(signal); % compute the FFT of the signal

%magX = abs(X); % magnitude of the FFT

%phaseX = angle(X); % phase of the FFT

figure;

plot(freq,X_mag,'LineWidth',1);

xlim([0 1000]);

xlabel('Frequency (Hz)');

ylabel('Acceleration (g)');

%savefig([field_names num2str(i) '.fig']);

end

You have all elements already in your code. Why not uncomment savefig and use files(i).name?

[Rajeev Kumar]

'savefig and use files(i).name' is not worked for save the all graph.

Your comment sounds like your issue is solved, but you didn't mark my answer as accepted. Can you confirm that your issue is resolved?

What code did you try and how did the result differ from what you want. I can't read your mind and I can't see your computer screen, so you will have to explain these things.
