vector or matrix with floating point entries or coefficients
- t
a boolean

isreal(x) returns true if x is
stored as a real variable and false if x is stored with
an (eventually zero) imaginary part.
isreal(x,eps) returns true if
x is stored as a real variable or if maximum absolute
value of imaginary floating points is less or equal than
eps.
