how to solve a error?

My error is

Error in training (line 6)
    I{a}=imread(['ImageDataSet/' num2str(a) '.tiff']);

Error in main (line 56)
         [traindata, trainlabel]=training(no_of_Image);

function program

function [trdata, trlabel]=training(no_input)
I=cell(no_input,1);
trdata=[];
trlabel=[];
for a=1:no_input
    I{a}=imread(['ImageDataSet/' num2str(a) '.tiff']);
end

k= 15;
option = 2;
for i=1:length(I)
 [kn]=mkuan(I{i});
 ad= anisodiff(kn,k,option);
 [Y] = FLDA(ad);
 data=reshape(Y,[1,size(Y,1)*size(Y,2)]);
 Label=reshape(Y>=max(Y(:)),[1,size(Y,1)*size(Y,2)]);
 trdata=[trdata data];
 trlabel=[trlabel Label];
end

You have a block of unreadable code (select your code and then click the {}Code button).

Without additional information, my best guess would be that the file doesn't exist.

error is here

Error using imread>get_full_filename (line 516) File "ImageDataSet/1.tiff" does not exist.

Error in imread (line 340) fullname = get_full_filename(filename);

Error in training (line 6) I{a}=imread(['ImageDataSet/' num2str(a) '.tiff']);

Error in main (line 56) [traindata, trainlabel]=training(no_of_Image);

[Walter Roberson]

We, as outsiders, have no reason to expect that file ImageDataSet/1.tiff is definitely going to be there.

You should be testing to see that the files are present before attempting to read them, or else you should be putting in a try/catch to handle the situation of the files not being available.

Then the answer is in the error message: the file does not exist. Note that your file separator depends on your system. That's the reason you shouldn't hardcode the slashes unless you're certain only 1 file system will handle this code. You can use filesep or fullfile instead. It might also be best to use an explicit path. You can use pwd to get the current directory, or use dbstack('-completenames') to get the folder of the function that is running.
