# 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.

• inv — matrix inverse
• percent — (%) special character
• backslash — left matrix division.
• ieee — set floating point exception mode
