# slash

(/) right division and feed back (comments)

## 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.

## Examples

    a=4 / 2; // Should be 2
    a=2 ./ [2,4]; //     1.    0.5
    // Comments are good. They help to understand code
