Pharo-NDArray

Package for multidimensional arrays and common array programming language algorithms.

Example

NDArray withAll: 9 iota "Step 1"
   :> reshape: #(3 3)   "Step 2"
   :> + 10              "Step 3"
   :> reduce: #+        "Step 4"
   :> asArray           "Step 5"

Each step of the above code creates the following:

"Step 1:"
1 2 3 4 5 6 7 8 9

"Step 2"
1 2 3
4 5 6
7 8 9

"Step 3"
11 12 13
14 15 16
17 18 19

"Step 4"
36 45 54

"Step 5"
36 45 54 "Array (no longer NDArray)"
