array handling

[ITElearner]

What I want to do.

Extract one dimension of a two dimension array into a new one dimension array.

Extract every eighth element into a calculation to build a new one dimension array.

Use the new array built above to calculate two new values into two new arrays using values from the original one dimension array.

Have a look at the help for "Index Array" and "Decimate 1D Array".  The Index array funtion will allow you to extract one dimension of the 2d array (row or column) and the Decimate 1D array will allow you to extract every nth element.
