XPRBquadExp& assign(XPRBquadExp& q)

Operators  (C++ only)

Assigning (elements to) quadratic expressions:

qexp1 += qexp2

qexp1 -= qexp2

qexp1 = qexp2

Composing quadratic expressions from quadratic and linear expressions (qexp and linexp), variables (var) and double values (val). The following operators, with the exception of the negation of a quadratic expression, are defined outside any class definition:

- qexp

qexp1 + qexp2

qexp1 - qexp2

var1 * var2

linexp * var

var * linexp

qexp * val

val * qexp

qexp1 * qexp2

Throws the exception `Non-quadratic expression' if the result of the operation is not quadratic

C++ only

Functions outside any class definition that generate quadratic expressions:

XPRBquadExp sqr(XPRBquadExp& Q)

XPRBquadExp sqr(XPRBlinExp& l)

XPRBquadExp sqr(XPRBvar& v)
