mat = dir('*.mat');
for q = 1:length(mat)
load(mat(q).name);
end
Hi, i see there is answer in https://www.mathworks.com/matlabcentral/answers/139879-how-to-read-all-mat-files-from-a-folder-in-matlab
However, you are mentioning you want to extract specific data from those files. As per my knowledge, may be we need to know what is the name of variable in the mat file first.
May be you can attach few of your mat file, and further elaborate it. So may be some of expert here can try it out.

Hi Suhas Goravale Siddaramu,
I have tried out your attached mat. file. I guess you are saying row 11 instead of column 11. In your mat.file, there is variable Pre-cell, it has 3 columns and 14 rows.
mat = dir('*.mat');
for q = 1:length(mat)
load(mat(q).name);
data(q,:) = Pre_cell(11,:)
end
with the additional line of code data(q,:) = Pre_cell(11,:), it will load all the row 11 of mat file into data.
Should you have any doubt, you may ask.

Whenever you wish to load all files, just use dir.
F=dir('*.mat')
for i =1:length(F)
load(F(i).name)
end
