i have an array, named ersum which have 20000 columns (1*20000). i need to find minimum value of first 50 columns. next minimum value of next 50 columns and so on upto last 50 in that 20000 columns. please send suitable code. thank you sir.
if ersum(:,counter)<ersum(:,counter+1) minind(:,k)=counter; else minind(:,k)=counter+1; ...

i had converted image into blocks. I converted blocks to linear array. Next i calculated mean values for first 8 arrays as given below. now i want to calculate values by using the formula: sum(linear array(:,1)-mean(:,1)).^2. please send code.
for i=1:4:nr-3 for j=1:4:nc-3 block=I(i:i+3,j:j+3); %convert 4X4...
