dsvdc.f90 Calculates the singular-value decomposition (SVD) of a real matrix. N.B. Algorithm 916 requires an external complementary error function erfc(x) function for real arguments x to be supplied as a subroutine. as177.f90 Calculates the expected values of normal order statistics. This package is for the numerical inversion of Laplace transforms. mace.f90 is an F90 version of Jerry Friedman's program to estimate multiple optimal transformations for regression and correlation by alternating conditional expectation estimates. ERFZ enhances ERF to evaluate the error function of complex numbers too. subset.f90 is a driver program which uses the above two modules.

Semenenk#3 / 3 Error Function of Complex Argument Hello everyone, Thanks to all, I have got the code I needed. I have included testfunc.f90 which will eventually contain all of Neumaier's 30 test functions. There is also a test program which may be useful test395.f90. double im_w_of_x (double x): The same for real x, returning the purely imaginary result as a real number.

The user must provide a subroutine to supply any requested row of the matrix. Tha main uses of this algorithm are likely to be for choosing designs in situations in which there are blocks of an awkward size, and for augmenting an experiment which has as135.f90 Min-Max (L-infinity) estimates for linear multiple regression, includes a test program. Levenberg-Marquardt algorithm for non-linear least squares (unconstrained).

I fixed our code to avoid using erfc because I also need to parallelize those codes, like changed erfc to... !erfc function t=1.0 / (1.0 + 0.3275911 * x ) xsqq=x KLVNB: Kelvin functions ber(x), bei(x), ker(x), and kei(x), and derivatives. It can use differences instead of derivatives, and bounds may be imposed on the parameters. License: MIT License When using libcerf in scientific work, please cite as follows: S.

The present library libcerf provides the missing implementation, along with a related functions. t_minim.f90 is a very simple test program for minim.f90 which may help users.

Opens overlay T.A Zaker Engineering Mechanics Division I.I.T. lanczos.f90 A simple algorithm for the logarithm of the gamma function.

CLPN computes Legendre functions and derivatives for complex argument. Code written by other authors or from other sources (e.g., academic journals) may be subject to other restrictions. For statistical software in a variety of languages try statlib. Complex trig functions for large imaginary arguments 4.

Includes a short driver program, and hence includes the interfaces needed for your program.
