Section: Basic Matrix functions

Name: ||<->

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

Both matrices a and b must have the same size and dimension. The resulting matrix c is of the same size, type and dimension.
Supported types: [ int,float,complex ]
[ c:('a, 'b, 'c) Matrix.t ] =
a:('a, 'b, 'c) Matrix.t ||<->
b:('a, 'b, 'c) Matrix.t

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>
