I have an array of 10001 elements of which a 2x2 matrix is inside each element. How can I loop thru the array and extract the first row, first column of each matrix?
Will appreciate your feedback.

@Mr. NailGuy: your array description is wildly inaccurate. The screenshot clearly shows that your array has size 2x2x10001, which means that it actually has 40004 elements.
You might like to consider revising basic MATLAB terminology, if you want to communicate effectively with regular MATLAB users.

a=randi([1 10],2,2,10001);%a numeric array
row=a(1,:,:);
column=a(:,1,:);

Use squeeze,
all_first_elements = squeeze(your_matrix(1,1,:));
now, plot like you normally do,
plot(all_first_elements)
