# Nested Arrays and Logic Calculations

## Nested Arrays and Logic Calculations

(OP)
I have a series of mXn nested arrays with each of the elements as a {k,1}. I am trying to go in and find the max of each of the k values within each element. For example, max( A[mXn [space] [space] [k , B[mXn [space] [space] [k , C[mXn [space] [space] [k ). I want to return a mXn nested array with elements as a {k,1}. I can't seem to get the syntax to do this in one step.

If doing this in one step is not possible, I have found that max( A[mXn [space] [space] [k , B[mXn [space] [space] [k , C[mXn [space] [space] [k ) outputs a matrix which is (k*m*n)X1. Is there a way chop the matrix into {k,1} vectors and nest them back into a mXn array?

Any help would be very much appreciated

### RE: Nested Arrays and Logic Calculations

Post a worksheet. My eyes glaze over trying to follow your [space][space].. thing.

### RE: Nested Arrays and Logic Calculations

Why wouldn't it just be:

maxarray[m,n := max(A[m,n)

I couldn't make heads or tails from your sheet.  It looks like you're defining k m*n arrays, not an m*n array of length-k vectors.

### RE: Nested Arrays and Logic Calculations

Are you trying to add/subtract 3 Matrices A, B, C, which in themselves are nested, in four different Variations and, after you have done that, find the the local maxima of the arrays [200,1]?
