In a folder I have 50 images of 5 subjects 10 each. (all are .jpg format) I named them as
sub1 (1)
sub1 (2)
...
...
sub1 (10)
sub2 (1)
sub2 (2)
...
...
...
...
..
sub5 (10)
I want to read them in matlab.
I have written following code in matlab
for i=1:5
for j=1:10
name=strcat('sub',int2str(i), ,'(',int2str(j),')','.jpg');
I=imread(name);
% some code
% some code
end
end
in the above code problem is with strcat can you please correct the above code. and can you give any alternative way to read all these images from the folder ?

@Raviteja: A space is *not* a null character. Does my answer using SPRINTF solve your problem?

Unfortuanely STRCAT removes marginal spaces from its inputs:
strcat('a', ' ', 'b')
>> ab
This was necessary when string lists have been implemented as CHAR matrices before CELLs have been invented - if I remember correctly this happend in Matlab 4.1.2. Using the CAT command is not influenced by this "smart" unblanking.
For your problem SPRINTF seems to be more convenient and it is not influenced by spaces:
name = sprintf('sub%d (%d).jpg', i, j);

for i=1:5 for j=1:10; strcat('d',int2str(i),int2str(j))=a(i,:)-b(j,:)

We cannot run this snipplet as a and b are missing. Further, I think it would be better if you start a new question with an appropriate title instead of posting an answer to a 4 year old question that contains another question...

for i=1:50 { A=imread(strcat('your image path\','iMAGE STARTING LETTER',int2str(i),'.bmp')); figure;imshow(A); }
