MATLAB: How to do this Data analysis

data analysis

I am having 5 .mat files. Each mat file contains 5 parameters. A,B,C,D,E
Now I want to plat a graph which will be considering all mat files.
I want to take C variable which is of a size 200×1 from each mat file, take mean of it for that mat file and then plot it against time.
So at the end I will get a graph with 5 points representing mean of the respective C columns from .mat file.
Can anyone help me to do this?
Here is what I have done till now:
clear all; clc;
myFolder = 'C:\Users\adi\Documents\MATLAB\';
if ~isdir(myFolder)
  errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
  uiwait(warndlg(errorMessage));
  return;
end
filePattern = fullfile(myFolder, '*.mat');
matFiles = dir(filePattern);
for k = 1:length(matFiles)
end
This is reading the files from my folder. Now Please help me to analyze them!

In the body of your for loop, write
 load(matFiles(k).name)
 plot(k, mean(C), '.')
 if k == 1, hold on, end
