Ports 搜索

This virtual port is Japanese Font Set for math/ngraph. This virtual port is for the ngraph user who can't use True Type Font under X. If you can use True Type Font with X True Type Server(aka X-TT) or X True Type Font Server(xfs.xtt), use True Type Font and don't use this ports. SEE ALSO math/ngraph description file

ised is a command-line tool for generating number sequences and arithmetic evaluation. Unlike big gui-based software (e.g. Mathematica, Derive, Matlab, Octave,...) it is intended for use in shell scripting, together with gnu core utilities. Its main advantage is that all functions are generalized to operate on one-dimensional arrays. It can be used for loop indexing (much like seq), line-by-line arithmetic processing of files, floating point math for shells that don't support it natively, or interactively, as extended calculator.

This class is a container class for numbers with a number of associated symmetric and asymmetric errors. It overloads practically all common arithmetic operations and trigonometric functions to propagate the errors. It can do proper scientific rounding (as explained in more detail below in the documentation of the significant_digit() method). You can use Math::BigFloat objects as the internal representation of numbers in order to support arbitrary precision calculations. Errors are propagated using Gaussian error propagation. With a notable exception, the test suite covers way over ninety percent of the code. The remaining holes are mostly difficult-to-test corner cases and sanity tests. The comparison routines are the exception for which there will be more extensive tests in a future release.

avr-libc -- a C and math library for the Atmel AVR controller family This library implements a subset of common C library functions, some Atmel AVR specific additions (like handling AVR's IO facilities, EEPROM etc.), as well as a 32-bit floating point math library (-lm). Everything is designed and implemented to cooperate with avr-gcc and avr-binutils.

DateTime::Set is a module for date/time sets. It can be used to handle two different types of sets. The first is a fixed set of predefined datetime objects. For example, if we wanted to create a set of dates containing the birthdays of people in our family. The second type of set that it can handle is one based on the idea of a recurrence, such as "every Wednesday", or "noon on the 15th day of every month". This type of set can have fixed starting and ending datetimes, but neither is required. So our "every Wednesday set" could be "every Wednesday from the beginning of time until the end of time", or "every Wednesday after 2003-03-05 until the end of time", or "every Wednesday between 2003-03-05 and 2004-01-07".

The trader extension is a free open source stock library based on TA-Lib. It's dedicated to trading software developers requiring to perform technical analysis of financial market data. Alongside many indicators like ADX, MACD, RSI, Stochastic, TRIX the candlestick pattern recognition and several vector arithmetic and algebraic functions are present.

Univariate Autoregressive Markov Switching Models for Linear and Generalized Models

MatchIt selects matched samples of the the original treated and control groups with similar covariate distributions - can be used to match exactly on covariates, to match on propensity scores, or perform a variety of other matching procedures.

Infrastructure for extended formulas with multiple parts on the right-hand side and/or multiple responses on the left-hand side.
