EIGEN_STRONG_INLINE const CwiseUnaryOp<internal::scalar_abs2_op<Scalar>, const Derived> cwiseAbs2

(

)

const

Returns

an expression of the coefficient-wise squared absolute value of *this

Example:

Output:

cwiseAbs()

Definition at line 31 of file MatrixCwiseUnaryOps.h.

const CwiseUnaryOp<std::binder1st<std::equal_to<Scalar> >, const Derived> cwiseEqual ( const Scalar &  s ) const

inline

Returns

an expression of the coefficient-wise == operator of *this and a scalar s

Warning

this performs an exact comparison, which is generally a bad idea with floating-point types. In order to check for equality between two vectors or matrices with floating-point coefficients, it is generally a far better idea to use a fuzzy comparison as provided by isApprox() and isMuchSmallerThan().
