I am trying to read image from one folder and save new images in different folder with different names. I need all of them in different names because they are generated with different affine2d values. For example images in a1 folder will be aa1,aa2,aa3,aa4,aa5.... and images in a2 folder will be bb1,bb2,bb3.... is there any way for do that ?
srcFiles = dir('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\*.jpg');
for i = 1 : length(srcFiles)
filename = strcat('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\',srcFiles(i).name);
im = imread(filename);
aform = affine2d([1 0 0; .1 1 0; 0 0 1])
bform = affine2d([1 0 0; .2 1 0; 0 0 1])
cform = affine2d([1 0 0; .3 1 0; 0 0 1])
dform = affine2d([1 0 0; .4 1 0; 0 0 1])
eform = affine2d([1 0 0; .5 1 0; 0 0 1])
fform = affine2d([1 0 0; .6 1 0; 0 0 1])
gform = affine2d([1 0 0; .7 1 0; 0 0 1])
hform = affine2d([1 0 0; .8 1 0; 0 0 1])
jform = affine2d([1 0 0; .9 1 0; 0 0 1])
a = imwarp(im,aform);
b = imwarp(im,bform);
c = imwarp(im,cform);
d = imwarp(im,dform);
e = imwarp(im,eform);
f = imwarp(im,fform);
g = imwarp(im,gform);
h = imwarp(im,hform);
j = imwarp(im,jform);
newfilename=strcat('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\a1\',srcFiles(i).name);
newfilename1=strcat('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\a2\',srcFiles(i).name);
newfilename2=strcat('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\a3\',srcFiles(i).name);
newfilename3=strcat('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\a4\',srcFiles(i).name);
newfilename4=strcat('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\a5\',srcFiles(i).name);
newfilename5=strcat('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\a6\',srcFiles(i).name);
newfilename6=strcat('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\a7\',srcFiles(i).name);
newfilename7=strcat('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\a8\',srcFiles(i).name);
newfilename8=strcat('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\a9\',srcFiles(i).name);
imwrite(a,newfilename,'jpg');
imwrite(b,newfilename1,'jpg');
imwrite(c,newfilename2,'jpg');
imwrite(d,newfilename3,'jpg');
imwrite(e,newfilename4,'jpg');
imwrite(f,newfilename5,'jpg');
imwrite(g,newfilename6,'jpg');
imwrite(h,newfilename7,'jpg');
imwrite(j,newfilename8,'jpg');
end

What's wrong with the way you did it?

code is working , its generating images and saving them but for example it is saving images as 1.jpg,2.jpg,3.jpg.....180.jpg in a1 file and also in a2 file or a9.
But i wanna change it, For example in a1 folder i wanna save images as aa1.jpg, aa2.jpg , aa3.jpg... etc and i wanna save images in a2 folder as ab1.jpg , ab2.jpg....
Because i am gonna put all these images in alexnet so they will be in same folder for training.
All of them need to have special name so i wont lose any data.
Until now i was just generating these images using same code and later i was using another code for rename all images in every file. So its kinda wasting time thats why i am trying to save them with different name when i am generating these images

Based on above information I'm assuming that the value of srcFiles(i).name is 'i.jpg'
Change the line
newfilename=strcat('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\a1\',srcFiles(i).name);
to
newfilename=strcat('C:\Users\mstfy\Desktop\Matlab\alex\Train1\Person1\a1\aa',srcFiles(i).name);
Do the same to newfilename1, newfilename2,..newfilename8.
Make sure you create the folders a1, a2 ....a9 in the folder Person1 before itself using mkdir.
