Data extraction from multiple matfiles.

Hello,
The following script loads all the files. The example of data is attached. I want to extract data for specific row and col for all the files i have (i.e., SM1,SM2,SM3,SM3). So i want code at commented place below in the script.
FileInfo=dir('SM*.mat');
for k= 1:length(FileInfo)
fileName=['SM' num2str(k)];
dataStruct.(fileName)=load([fileName '.mat']);
% This the place i want to have the way of extracting a pixel for all matfiles.
end
Thanks

How is the data stored in mat file? YOu extract the variable you want.
It is better if you could upload the mat file here, and state what variable you want to extract.

Your Question:
I want to extract data for specific row and col for all the files i have (i.e., SM1,SM2,SM3,SM3).
For example, if you want to extract row 1 and column 2 from the variable in the mat file. Let assume that SM1 has variable sm1, SM2 has variable sm2,......
FileInfo=dir('SM*.mat');
for k= 1:length(FileInfo)
fileName=['sm' num2str(k)];
dataStruct=load(FileInfo(k).name);
% This the place i want to have the way of extracting a pixel for all matfiles.
dataStruct.(fileName)(1,2)
end
