I need help using Scilab to average an 100x100x100 matrix in 2x2x2 cubes

Question

I am using Scilab to average an 100x100x100 matrix in 2x2x2 cubes.How can I change this script so that it averages it in 9x9x9 cubes?I know 100^3 doesn't divide evenly into 9x9x9 cubes.I just want to average it until it can no longer be evenly diveded.

a=1 b=1 c=1 numbers = rand(100,100,100) while c <=99, if a>99 then a=1 b=b+2 c=1; end if b>99 then a=1 b=1 c=c+2; end average=(numbers(a,b,c)+numbers(a+1,b,c)+numbers(a,b+1,c)+numbers(a+1,b+1,c) +numbers(a,b,c+1)+numbers(a+1,b,c+1)+numbers (a,b+1,c+1)+numbers(a+1,b+1,c+1))/8
a=(a+2); end

Answer 1

You need to use the matrix function that is built into scilab. Simply use this at each iteration with cubes of the desired size.

Answer 2

Not exactly sure what you want but:

mean(numbers(1:9, 1:9, 1:9))

is probably what you need.
