NSamples=25; NClasses=9;
for i =1:T
for s=1:NSamples
for c=0:NClasses
%traitement---------------------------------------------------------
img=imread([P I(i).name]);
R = imresize (img,[100 100]);
G = rgb2gray(R);
BW1 = edge(G,'sobel');
classfile =mkdir( sprintf('c%d',c));
imgfile = sprintf('%d.png',s);
fulfile = fullfile(classfile,imgfile);
dir_file = dir(fulfile)
imwrite(BW1,dir_file);
end
end
end

In the code below I fixed some issues with your code. Compare the lines I changed and read the documentation for those functions to better understand their input and output. Especially the output for mkdir and dir.
for c=0:NClasses
classfoldername=sprintf('c%d',c);
if ~exist(classfoldername,'dir')
mkdir(classfoldername);
end
end
for i =1:T
for s=1:NSamples
for c=0:NClasses
%traitement---------------------------------------------------------
img=imread([P I(i).name]);
R = imresize (img,[100 100]);
G = rgb2gray(R);
BW1 = edge(G,'sobel');
classfoldername=sprintf('c%d',c);
imgfile = sprintf('%d.png',s);
fulfile = fullfile(classfoldername,imgfile);
imwrite(BW1,fulfile);
end
end
end
