Revert "do a little bit better job compressing the bytes"
This reverts commit 099a35881e.
Revert "adjust file to use the literal bytes for the ufo image"
This reverts commit fdd9344b27.
* Consolidated Gauss and Gauss-Jordan elimination
* Fixed Gaussian elimination to return all indexes for pivotless columns,
not just those < m
* Consolidated `matrix-row-echelon' and `matrix-reduced-row-echelon'
* Specialized row reduction for determinants; removed option to not do
partial pivoting (it's never necessary otherwise)
* Added `matrix-invertible?'
* Removed `matrix-solve-many'; now `matrix-solve' solves for multiple
columns
* Gave `matrix-inverse' and `matrix-solve' optional failure thunk arguments
* Made some functions that return multiple columns return arrays instead
(i.e. `matrix-column-space')
* Added more tests
The version number is included as the query part of the constructed
URL, so it is easily ignored by a server. The intent is that the
PLT PNRs will eventually support version-specific results.
* 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.
JPEG reading and writing involve callbacks that need to be
atomic, since the stack-swapping games that a Racket thread
switch plays may not be ok with the JPEG library (as exposed
by the stress test). So, the JPEG reading and writing code
must read/write a string port, instead of directly from/to
the source/destination port, since a string port can be
used in atomic mode.
More precisely, do this for nested flows with the "refcontent" style.
For instance this Scribble:
@margin-note{Note: This is a note. Let's make it long enough that the
markdown output will have to line-wrap, to make sure the > mark starts
each line properly.}
Will render as this Markdown:
> Note: This is a note. Let's make it long enough that the markdown output
> will have to line-wrap, to make sure the > mark starts each line
> properly.
A site like GitHub.com will render this in a block-quote style
suitable for notes:
> Note: This is a note. Let's make it long enough that the markdown output
> will have to line-wrap, to make sure the > mark starts each line
> properly.
A phantom byte string is a small object that the memory
manager treats as an arbitrary-sized object, where the
size is specified when the phantom byte string is created
or or when size is changed via `set-phantom-bytes!'.
Things should now generally be set up to work better --
for example online check syntax is smarter now about
what happens when switching tabs/frames and this also
makes it easier to add new ways for a window to become
dirty (that is, for it to be known that it needs to
be recompiled)
Keep track of whether any Racket-managed subprocesses are pending,
and use waitpid(0, ...) only if there is one, to better cooperate
with an embedding environment.
Also, add a chapter to the "Inside" manual to explain the issues.
