Why is my loop not working?

dinfo = dir('M:\xxx\IDXX_xxx_xxx_XXXX.XX.XX_XX.XX.XX\**\**\*scrList.mat');
filenames = fullfile({dinfo.folder}, {dinfo.name});
numfiles = length(filenames);
for K = 1:numfiles
    thisfile = filenames{K};
    load (thisfile)
    plot (scrList.DDA.amp)
end

I have a folder with a lot of subfolders. I managed to read them all but when it comes to plotting it didnt really plot every file but only one file instead. Any suggestion how to fix that?

It will only plot the last file. You need to store the thisfile as array.

@Ankit could you tell me how, i am a newbie :D

You need to use hold on

dinfo = dir('M:\xxx\IDXX_xxx_xxx_XXXX.XX.XX_XX.XX.XX\**\**\*scrList.mat');
filenames = fullfile({dinfo.folder}, {dinfo.name});
numfiles = length(filenames);
for K = 1:numfiles
    thisfile = filenames{K};
    load (thisfile)
    plot (scrList.DDA.amp)
    hold on % Prevent subsequent plots from blowing away prior plots.
end

my goal is to showcase the plot of every file and not in one image

[Torsten]

Then use

figure(K) 
plot (scrList.DDA.amp)

within the loop.
