Hello, currently I have a 1024x1024 array in matlab that I have loaded in from a .txt file:
a = load('File.txt');
I want to find the mean, standard deviation, and the quartile ranges for this array. So far, I have only come across commands that return the average of each column or row, however I want to get basic statistical information when considering every element in the array. Is there a simple command or function that will just spit all this information out for me in a table? Any help is greatly appreciated.

Force the array into a vector, then use mean, std, the appropriate version of iqr, and the rest.
Example —
a_mean = mean(a(:));
and so for the other functions.

As always, my pleasure!
I addressed that in my Answer to your follow-up Question.

You could reshape the matrix into a vector, then apply the functions to the vector
