Error in Updating the text file

IntString2 = sprintf('<FileName>',cFile(i).name,'</FileName>')

and i get the below error message

"Subscript indices must either be real positive integers or logicals."

Would be great on any suggestions

Answer 1

Probably i starts from 0, it should start from 1 and it should be integer at any circumstances. This happens probably in a for loop. Please check it.

Probably i was not assigned a value and has its default association with sqrt(-1)
