The matrix Plugin More...

Classes
class	LowerMatrixHighLevelMapRed
	Resolves lowering of high level operations into medium/other high-level operations. More...
class	LowerMatrixLowLevel
	In this phase, we lower all matrix operations and types to the low-level representation using pointers. More...
class	LowerMatrixMediumLevel
	In this step, we lower map_reduce operations into affine for loops making the iteration scheme explicit. More...

• TODO: map_reduce (..., ((idx,map_reduce([out, ]...), ...))) -> unify idx, out (out is implicit), name vars apart requires: same reduction, distributive reduction we assume distributivity of the reduction function

• read(insert m v i, i) -> v (TODO: check with map_reduce)
• read(insert m v i, j) -> read(m, i) if i <> j (TODO: wanted? useful?)
• read(transpose m, (i,j)) -> read(m, (j,i)) (TODO: check for map_reduce)
• read(product m1 m2, (i,j)) -> ... (TODO: check with map_reduce)
• read (map_reduce f) idx = loop f idx (TODO: implement => use inner loop from lowering phase)

Normalizer for transpose operations.

• transpose (constMat v) -> cosntMat v (TODO: implement)
