Extract data from .dat and plot a curve

Hello Guys,

I am new to the MATLAB and have a question regarding .dat files.

I have multiple .dat files with data in first column.

What I want to do is to take an average of a data inside of every .dat file and plot it against the time.

For example,

CD001.dat corresponds to data at the time of 1 sec and so on...

I have nearly 1000 .dat files corresponding to different times.

I want to take the average of the data inside every .dat file and save it for a corresponding time.

Then, I want to plot every average value corresponding to the respective time.

How it can be done?
