# EigenR 1.2.3

Fixed a mistake in `Eigen_UtDU`.

# EigenR 1.2.2

No change for the user.


# EigenR 1.2.1

No change for the user.


# EigenR 1.2.0

New functions:

- `Eigen_pinverse` returns the pseudo-inverse (Moore-Penrose generalized 
inverse) of a matrix.

- `Eigen_absdet` returns the absolute value of the determinant of a real square 
matrix.

- `Eigen_logabsdet` returns the logarithm of the absolute value of the 
determinant of a real square matrix.

- `Eigen_isInjective`, `Eigen_isSurjective`, `Eigen_isInvertible` return a Boolean value.

- `Eigen_kernelDimension` returns the dimension of the kernel of a matrix.

- New method for `Eigen_lsSolve`, faster.


# EigenR 1.1.0

New matricial functions have been included: exponential, logarithm, cosine, 
sine, hyperbolic cosine, hyperbolic sine, power, square root. They all support 
complex matrices.


# EigenR 1.0.0

First release.
