data = xlsread ('file.xlsx' ,'sheet');
k=15;
for i = 1:16:128
    for j= 1:16:128
    submat = data(i:i+k,j:j+k);
    Uniform(i,j) = (max(max(submat)))/(min(min(submat)))
    end

In given code i want to store values i am getting for Uniform vector to 8 by 8 matrix. Problem here is since this has a step of 16 normal methods did not work.

Thnak you

Method 1:

data = xlsread ('file.xlsx' ,'sheet');
k=15;
for i = 1:16:128
    for j= 1:16:128
    submat = data(i:i+k,j:j+k);
    Uniform((i-1)/16+1,(j-1)/16+1) = (max(max(submat)))/(min(min(submat)))
    end

Method 2:

data = xlsread ('file.xlsx' ,'sheet');
k=15;
count_i = 1;
for i = 1:16:128
    count_j = 1;
    for j= 1:16:128
    submat = data(i:i+k,j:j+k);
    Uniform(count_i,count_j) = (max(max(submat)))/(min(min(submat)))
    count_j = count_j + 1;
    end
    count_i = count_i + 1;
