I want to sort a set of images whose data is given in .csv format.
The data consists of three different types in three columns, by indicating 1 for the specific type and 0 if not.
I want to separate it the whole set of images into three folders using the given .csv data.
Please help.

I'm a little confused on what you are asking for. Does each column independently represent an image, and you want to separate the columns into unique files? Or does the data contain three columns and a certain number of rows and you want to separate the data by those rows?

The data contains four columns in total, where the first is the file name rest three and three different classes which I want them to classify it into.
In each of the column of the classes it is either a 1 or a 0 corresponding to the file name.
I hope this gives a little more clarity now.

Ok, so you're trying to collect a set of file names?

I would suggest organizing using indexing then.

A = % Data block here
B = A(A(:,2)==1,1); % Select file names (column 1) which corresponds to 1's
                    & in column 2.
C = A(A(:,3)==1,1); % 1's in column 3
D = A(A(:,4)==1,1); % 1's in column 4
