Hello,
I want to implement matrix approximation using SVD.
The SVD algorithm returns three boxed matrices of the shapes x x ; x y ; y y
I want to chop and multiply back:
Step 1: reshape as - x M; M M ; M y where M is a small value
Step 2: Unbox and multiply (x M * M M * M y = x y)
My current
'x y M'=. 5 7 3 NB. Parameters
$.s=. (i.x,x);(i.x,y);i.y,y NB. Fake s
+---+---+---+
|5 5|5 7|7 7|
+---+---+---+
2\x,M,M,y NB. Shapes we want
+---+---+---+
|5 3|3 3|3 7|
+---+---+---+
(2\xx,M,M,yy){..s
++++
| 0 1 2| 0 1 2| 0 1 2 3 4
