MATLAB: Data extraction from multiple matfiles.

data extraction

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

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
