/** \class NumTraits
*
* \brief Holds some data about the various numeric (i.e. scalar) types allowed by Eigen.
* \brief Holds information about the various numeric (i.e. scalar) types allowed by Eigen.
*
* \param T the numeric type about which this class provides data. Recall that Eigen allows
* only the following types for \a T: \c int, \c float, \c double,
* \c std::complex<float>, \c std::complex<double>, and \c long \c double (especially
* useful to enforce x87 arithmetics when SSE is the default).
* \param T the numeric type at hand
*
* The provided data consists of everything that is supported by std::numeric_limits, plus:
* This class stores enums, typedefs and static methods giving information about a numeric type.
*
* The provided data consists of:
* \li A typedef \a Real, giving the "real part" type of \a T. If \a T is already real,
* then \a Real is just a typedef to \a T. If \a T is \c std::complex<U> then \a Real
* is a typedef to \a U.
* \li A typedef \a FloatingPoint, giving the "floating-point type" of \a T. If \a T is
* \c int, then \a FloatingPoint is a typedef to \c double. Otherwise, \a FloatingPoint
* is a typedef to \a T.
* \li A typedef \a NonInteger, giving the type that should be used for operations producing non-integral values,
* such as quotients, square roots, etc. If \a T is a floating-point type, then this typedef just gives
* \a T again. Note however that many Eigen functions such as ei_sqrt simply refuse to
* take integers. Outside of a few cases, Eigen doesn't do automatic type promotion. Thus, this typedef is
* only intended as a helper for code that needs to explicitly promote types.
* \li A typedef \a Nested giving the type to use to nest a value inside of the expression tree. If you don't know what
* this means, just use \a T here.
* \li An enum value \a IsComplex. It is equal to 1 if \a T is a \c std::complex
* type, and to 0 otherwise.
* \li An enum \a HasFloatingPoint. It is equal to \c 0 if \a T is \c int,
* and to \c 1 otherwise.
* \li An enum value \a IsInteger. It is equal to \c 1 if \a T is an integer type such as \c int,
* and to \c 0 otherwise.
* \li Enum values ReadCost, AddCost and MulCost representing a rough estimate of the number of CPU cycles needed
* to by move / add / mul instructions respectively, assuming the data is already stored in CPU registers.
* Stay vague here. No need to do architecture-specific stuff.
* \li An enum value \a IsSigned. It is equal to \c 1 if \a T is a signed type and to 0 if \a T is unsigned.
* \li An epsilon() function which, unlike std::numeric_limits::epsilon(), returns a \a Real instead of a \a T.
* \li A dummy_precision() function returning a weak epsilon value. It is mainly used by the fuzzy comparison operators.
* \li Two highest() and lowest() functions returning the highest and lowest possible values respectively.
* \li A dummy_precision() function returning a weak epsilon value. It is mainly used as a default
* value by the fuzzy comparison operators.
* \li highest() and lowest() functions returning the highest and lowest possible values respectively.

* one of the coords as a linear (affine) function of the other coords.
*
* This is best explained by an example. This function works in full
* generality, for points in a space of arbitrary dimension, and also over
* the complex numbers, but for this example we will work in dimension 3
* over the real numbers (doubles).
*
* So let us work with the following set of 5 points given by their
* \f$(x,y,z)\f$ coordinates:
* @code
Vector3d points[5];
points[0] = Vector3d( 3.02, 6.89, -4.32 );
points[1] = Vector3d( 2.01, 5.39, -3.79 );
points[2] = Vector3d( 2.41, 6.01, -4.01 );
points[3] = Vector3d( 2.09, 5.55, -3.86 );
points[4] = Vector3d( 2.58, 6.32, -4.10 );
* @endcode
* Suppose that we want to express the second coordinate (\f$y\f$) as a linear
* expression in \f$x\f$ and \f$z\f$, that is,
* \f[ y=ax+bz+c \f]
* for some constants \f$a,b,c\f$. Thus, we want to find the best possible
* constants \f$a,b,c\f$ so that the plane of equation \f$y=ax+bz+c\f$ fits
* best the five above points. To do that, call this function as follows:
* @code
Vector3d coeffs; // will store the coefficients a, b, c
linearRegression(
5,
&points,
&coeffs,
1 // the coord to express as a function of
// the other ones. 0 means x, 1 means y, 2 means z.
);
* @endcode
* Now the vector \a coeffs is approximately
* \f$( 0.495 , -1.927 , -2.906 )\f$.
* Thus, we get \f$a=0.495, b = -1.927, c = -2.906\f$. Let us check for
* instance how near points[0] is from the plane of equation \f$y=ax+bz+c\f$.
* Looking at the coords of points[0], we see that:
* \f[ax+bz+c = 0.495 * 3.02 + (-1.927) * (-4.32) + (-2.906) = 6.91.\f]
* On the other hand, we have \f$y=6.89\f$. We see that the values
* \f$6.91\f$ and \f$6.89\f$
* are near, so points[0] is very near the plane of equation \f$y=ax+bz+c\f$.
*
* Let's now describe precisely the parameters:
* @param numPoints the number of points
* @param points the array of pointers to the points on which to perform the linear regression
* @param result pointer to the vector in which to store the result.
This vector must be of the same type and size as the
data points. The meaning of its coords is as follows.
For brevity, let \f$n=Size\f$,
\f$r_i=result[i]\f$,
and \f$f=funcOfOthers\f$. Denote by
\f$x_0,\ldots,x_{n-1}\f$
the n coordinates in the n-dimensional space.
Then the resulting equation is:
\f[ x_f = r_0 x_0 + \cdots + r_{f-1}x_{f-1}
+ r_{f+1}x_{f+1} + \cdots + r_{n-1}x_{n-1} + r_n. \f]
* @param funcOfOthers Determines which coord to express as a function of the
others. Coords are numbered starting from 0, so that a
value of 0 means \f$x\f$, 1 means \f$y\f$,
2 means \f$z\f$, ...

/** \ingroup LeastSquares_Module
*
* \leastsquares_module
*
* This function is quite similar to linearRegression(), so we refer to the
* documentation of this function and only list here the differences.
*
* The main difference from linearRegression() is that this function doesn't
* take a \a funcOfOthers argument. Instead, it finds a general equation
* of the form
* \f[ r_0 x_0 + \cdots + r_{n-1}x_{n-1} + r_n = 0, \f]
* where \f$n=Size\f$, \f$r_i=retCoefficients[i]\f$, and we denote by
* \f$x_0,\ldots,x_{n-1}\f$ the n coordinates in the n-dimensional space.
*
* Thus, the vector \a retCoefficients has size \f$n+1\f$, which is another
* difference from linearRegression().
*
* In practice, this function performs an hyper-plane fit in a total least square sense
* via the following steps:
* 1 - center the data to the mean
* 2 - compute the covariance matrix
* 3 - pick the eigenvector corresponding to the smallest eigenvalue of the covariance matrix
* The ratio of the smallest eigenvalue and the second one gives us a hint about the relevance
* of the solution. This value is optionally returned in \a soundness.

In this section we will see how to add custom methods to MatrixBase. Since all expressions and matrix types inherit MatrixBase, adding a method to MatrixBase make it immediately available to all expressions ! A typical use case is, for instance, to make Eigen compatible with another API.
You certainly know that in C++ it is not possible to add methods to an extending class. So how that's possible ? Here the trick is to include in the declaration of MatrixBase a file defined by the preprocessor token \c EIGEN_MATRIXBASE_PLUGIN:
