Hi, I had a 7000x4000 Matrix of topographic data that I split into 10x10 matrices (Split by going every 10 rows and 10 columns) using this code:
filename = '1m_studyarea_data.xlsx';
A = xlsread(filename);
B=mat2cell(A,10*ones(400,1),10*ones(700,1))
C=cellfun(@(x) x(randi(100)),B)
I need it to randomly select 1 number out of the 100 in each matrices using normal distribution?
Thanks, Akshay

You asked this exact question before. What was wrong about that answer? The only difference is that you have now asked how to randomly select 1 number using the normal distribution, whereas the last time, you just stated a random requirement, with no distribution. Since a normal distribution is unbounded, your question makes no mathematical sense.
