Description 
QuasiQuoting for matrices and vectors.
BIG WARNING: the expression quasiquoters for matrices and vectors
are broken for infix expressions. All operators will be assumed to
be left infix with infix level 9. To avoid unexpected parses, fully
parenthesise all infix expressions.


Synopsis 



Documentation 


The matrix quasiquoter for expressions and patterns.
 Elements on the same row are separated by commas; rows
themselves are separated by semicolons. All whitespace is optional
 The expression quasiquoter allows arbitrary Haskell
expressions as its elements; the pattern quasiquoter
requires that each element is a variable.
 Using the quasiquoter for patterns requires that you
use the viewMat view pattern first (this is a
workaround since Template Haskell doesn't yet support
view patterns).
For example,
example1 :: (Element t) => Matrix (D2,D3) t > Matrix (D2,D2) t
example1 (viewMat > [$mata, b, c;
d, e, f]) = [$mata+b, b+c;
sin c, f ] 


Quasiquoter for matrices of Unknown size. We should
just use [$matU<text>] as shorthand for forgetShapeU [$mat<text>].
No pattern quasiquoter exists, and I currently have
no plans to introduce one.



The vector quasiquoter for expressions and patterns. This is
very similar to the mat quasiquoter.
 Elements are separated by commas; whitespace is ignored.
 The expression quasiquoter allows arbitrary Haskell expressions for
each element; the pattern quasiquoter requires that each element is
a variable pattern.
 The pattern quasiquoter must be preceeded by a the viewVec view pattern.
For example,
example2 :: (Storable t, Num t) => Vector D2 t > Vector D3 t
example2 (viewVec > [$veca, b]) = [$veca*b, 5, 7] 


Quasiquoter for vectors of unknown lengths. Like matU,
[$vecU<text>] is just shorthand for forgetShapeU [$vec<text>].
