Hi all,

I am using matrix division instead of matrix inverse. Page 480 shows the operation:

`matrix **operator/**(matrix B, matrix A)`

but I I write

`operator/((P * [[phi1^deltat[k], 0], [0, phi2^deltat[k]]]), P)`

it warns that variable “operator” does not exist. Do you have any idea?

Kind regards,

Trung Dung.
