Section: Basic Matrix functions

Name: ||<-.>

Subtract a constant b from the elements of the matrix a.
The result is stored in a new allocated matrix c.
c.{i,j,k,...} <- a.{i,j,k,...} - b

Supported types: [ int,float,complex ]
[ c:('a, 'b, 'c) Matrix.t ] =
a:('a, 'b, 'c) Matrix.t ||<->
b:'a

Example: 
[] let i = imatrix ~dim:[50;40] ~rand:[1000] () ;; 
val i : (int, '_a, '_b) Matrix.t = <abstr> 
[] let j = imatrix ~dim:[50;40] ~rand:[1000] () ;; 
let j = imatrix ~dim:[50;40] ~rand:[1000] () ;; 
[] let c = i ||<-> j ;; 
val c : (int, '_a, '_b) Matrix.t = <abstr>

With the operator ||<.-> , the matrix and constant are interchanged.
