Question

i am searching a folder for text files and i am adding those files found into a new array called mytext

this is my code

function fileList = removeElements(fileArray)

x = 1;
mytext = [];

for idx = 1:numel(fileArray)

if (~isempty(strfind(fileArray(idx),'.txt')  )) 

    mytext(x) = fileArray(idx)
    x=x+1;  

end 

end

end

But iam getting a error

??? The following error occurred converting from cell to double:
Error using ==> double
Conversion to double from cell is not possible.

Error in ==> removeElements at 10
        mytext(x) = fileArray(idx)

How can i overcome this ?

Answer 1

Strings are generally stored in cell arrays. So you need to index with {}, not ():

mytext{x} = fileArray{idx};
