MATLAB: Finding Statistics of a Matrix Help!!!

arrayMATLABmatrixstatistics

Hello, currently I have a 1024×1024 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.
