(/) right division and feed back
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.
