Open files in loop and perform operations

I have many files of the type data_1_9.txt, data_1_15.txt, data_2_9.txt, data_2_15.txt, data_3_9.txt, data_3_15.txt, .........data_200_9.txt, data_200_15.txt.

I need to open two files at a time, perform some operations and then save it to a file.Something like this

load data_1_9.txt, data_1_15.txt

perform some operations

save it as something like data_1.txt

similarly for all 200 files

How can i write a for loop for this operation

Hi

The following routine might help your task.

You can use the dir function to get the names of all the text files in a directory.

Once you have the list you can simply use a for loop with a step size of 2 and load consecutive file and perform your operation.

fprintf will help you in writing the output text file.

Hope this helps.

Thanks
