# slash

(/) right division and feed back

### Description

Right division. `x=A / b`

is the solution of `x*b=A`

.

`b/a = (a' \ b')'`

.

`a./ b`

is the matrix with entries `a(i,j)/ b(i,j)`

.
If `b`

is scalar (1x1 matrix) this operation is the same
as `a./b*ones(a)`

. (Same convention if `a`

is a scalar).

Remark that `123./b`

is interpreted as `(123.)/b`

. In this
cases dot is part of the number not of the operator.

Backslash stands for left division.

System feed back. `S=G/.K`

evaluates
`S=G*(eye()+K*G)^(-1)`

this operator avoid simplification problem.

Remark that `G/.5`

is interpreted as `G/(.5)`

. In such
cases dot is part of the number, not of the operator.

Comment `//`

comments a line i.e. lines which begin by `//`

are ignored by the interpreter.
