* Split "matrix-constructors.rkt" into three parts:
* "matrix-constructors.rkt"
* "matrix-conversion.rkt"
* "matrix-syntax.rkt"
* Made `matrix-map' automatically inline (it's dirt simple)
* Renamed a few things, changed some type signatures
* Fixed error in `matrix-dot' caught by testing (it was broadcasting)
* Rewrote matrix comprehensions in terms of array comprehensions
* Removed `in-column' and `in-row' (can use `in-array', `matrix-col' and
`matrix-row')
* Tons of new rackunit tests: only "matrix-2d.rkt" and
"matrix-operations.rkt" are left (though the latter is large)
* Finally added `array-axis-expand' as a dual for `array-axis-reduce'
in order to implement `vandermonde-matrix' elegantly
* Better, shorter matrix multiply; reworked all matrix arithmetic
* Split "matrix-operations.rkt" into at least 5 parts:
* "matrix-operations.rkt"
* "matrix-basic.rkt"
* "matrix-comprehension.rkt"
* "matrix-sequences.rkt"
* "matrix-column.rkt"
Added "matrix-constructors.rkt"
Added `matrix', `row-matrix', and `col-matrix' macros
A lot of other little changes
Currently, `in-row' and `in-column' are broken. I intend to implement
them in a way that makes them work in untyped and Typed Racket.
* `list->array' now accepts an optional shape argument, and always returns
an immutable array
* `vector->array' now accepts an optional shape argument, and always
returns a mutable array
* Removed `make-mutable-array' because `vector->array' does its job now (I
never liked the name anyway)
* Renamed `unsafe-mutable-array' to `unsafe-vector->array'
* Added optional type annotation to `array' macro to match `mutable-array'
* Reworded error messages in array broadcasting functions
* Made minor array doc fixes
renamed `partition-count' to `partitions' to be consistent with
`permutations', and gave better examples in `multinomial' docs
* (flulp-error +inf.0 +nan.0) was returning +nan.0 instead of +inf.0
* Type of `multinomial' didn't match its docs or `flmultinomial'
* Reworded docs for `diagonal-array'
* Reworked/reordered quite a few things in docs for `math/bigfloat'
* Fixed first identity given in `gamma-inc' docs
* Fixed descrption for `+max.0', etc.
* Fixed and added tests for `quantile' and `median', documented them
* Added `sort-samples', documented it
* Removed `real-quantile' and `real-median' (too many design choices
right now; will revisit when implementing Kernel Density Estimators)
* Documented `absdev' and `absdev/median'
* Fixed `update-statistics*': now uses O(1) space as advertised (if the
sequences of values and weights both use O(1) space)
* Changed types of binning functions: allows using #:key in the future
(when TR supports function type cases that differ only by keyword
argument types better), places optional weights at the end like other
statistics functions
* Clarified binning docs about sort stability and half-open intervals
Cleaned up expected value code a little
Refactored running statistics objects (hid private fields, added
`update-statistics*')
Documented expected value functions and running statistics
Removed `bfpsi0' from bigfloat tests (DrDr's libmpfr doesn't have it)
Commented out custodian shutdown callback that frees MPFR's cache
(something's broken)
of libmpfr (like DrDr's) that don't have it
Reimplemented really simple FFI functions (e.g. mpfr-prec, mpfr-exp) to
avoid calling overhead
Renamed `bigfloat-sign' to `bigfloat-signbit'
Renamed `bigfloat-sig+exp' to `bigfloat->sig+exp' (for symmetry with
`sig+exp->bigfloat')
Fixed bigfloat functions that assumed (fixnum? x) means x fits in a _long
(not true on Win64)
Hopefully fixed dangling pointer errors that broke `math/bigfloat' on Win64.
It apparently had no _long/_int mismatches, but GC on Win64 will run between
creating an `_mpz' and using its value after passing it as an output argument
to MPFR functions. That doesn't seem to happen on 64-bit Linux or Mac. No
idea why, but Win64 exposed the problem so... that's good, I guess.
Rewrote `rational->bigfloat' to not use GMP's rationals
More/better bigfloat tests
Added bigfloat stress test w/ weak leak detection
Reenabled custodian shutdown callback that clears MPFR constants, because it
seems to work now
Removed `mpfr-available?' because it would only return non-#f
original array strict instead of returning a new strict array.
(Finally!) The hard part is keeping the Array type covariant. The
solution is to keep the store in the closure of the array's
procedure instead of in the Array struct itself.
* bernoulli -> bernoulli-number
* farey -> farey-sequence
* fibonacci/mod -> modular-fibonacci
* order -> unit-group-order
* orders -> unit-group-orders
Documented `make-fibonacci' and `make-modular-fibonacci'
Reworked text about loading external libraries in docs for `math/bigfloat'
Removed type aliases like Z, Q, Prime (I like them, but TR was printing them
in unexpected places like array return types)
Replaced pointwise operators with macros that expand to applications of `array-map'; allows more precise return types and reduces compilation time
Changed literal array syntax to use #() to delimit rows instead of [] (still suggest using square parens, though)
Minor refactoring
Fixed a macro so that the only problem with "array-tests.rkt" now is that typed/rackunit is b0rked
in the original GitHub fork:
https://github.com/ntoronto/racket
Some things about this are known to be broken (most egregious is that the
array tests DO NOT RUN because of a problem in typed/rackunit), about half
has no coverage in the tests, and half has no documentation. Fixes and
docs are coming. This is committed now to allow others to find errors and
inconsistency in the things that appear to be working, and to give the
author a (rather incomplete) sense of closure.
