each line is my file which i want for further opration. if i would make an array for these file names, it would be easy for me.but i don't know how make a loop to read these characters from variables . hope u understand my question.

[the cyclist]

Create a cell array out of the character array:

c = cellstr(val);

Then, each cell element is a string that can be used:

c{1}

for example, is the first string. (Notice the use of curly brackets there.) You can read more about the use of cell array in the documentation.

[Stephen23]

Or without creating any intermediate cell array, simply use indexing directly:

for k = 1:size(val,1)
   one_name = val(k,:);
