;;; Commentary:
|
||
|
||
;; Calc is split into many files. This file is the main entry point.
|
||
;; This file includes autoload commands for various other basic Calc
|
||
;; facilities. The more advanced features are based in calc-ext, which
|
||
;; in turn contains autoloads for the rest of the Calc files. This
|
||
;; odd set of interactions is designed to make Calc's loading time
|
||
;; be as short as possible when only simple calculations are needed.

;;; TODO:
|
||
|
||
;; Fix rewrite mechanism to do less gratuitous rearrangement of terms.
|
||
;; Implement a pattern-based "refers" predicate.
|
||
;;
|
||
;; Make it possible to Undo a selection command.
|
||
;; Figure out how to allow selecting rows of matrices.
|
||
;; If cursor was in selection before, move it after j n, j p, j L, etc.
|
||
;; Consider reimplementing calc-delete-selection using rewrites.
|
||
;;
|
||
;; Implement line-breaking in non-flat compositions (is this desirable?).
|
||
;; Implement matrix formatting with multi-line components.
|
||
;;
|
||
;; Have "Z R" define a user command based on a set of rewrite rules.
|
||
;; Support "incf" and "decf" in defmath definitions.
|
||
;; Have defmath generate calls to calc-binary-op or calc-unary-op.
|
||
;; Make some way to define algebraic functions using keyboard macros.
|
||
;;
|
||
;; Allow calc-word-size=0 => Common Lisp-style signed bitwise arithmetic.
|
||
;; Consider digamma function (and thus arb. prec. Euler's gamma constant).
|
||
;; May as well make continued-fractions stuff available to the user.
|
||
;;
|
||
;; How about matrix eigenvalues, SVD, pseudo-inverse, etc.?
|
||
;; Should cache matrix inverses as well as decompositions.
|
||
;; If dividing by a non-square matrix, use least-squares automatically.
|
||
;; Consider supporting matrix exponentials.
|
||
;;
|
||
;; Have ninteg detect and work around singularities at the endpoints.
|
||
;; Use an adaptive subdivision algorithm for ninteg.
|
||
;; Provide nsum and nprod to go along with ninteg.
|
||
;;
|
||
;; Handle TeX-mode parsing of \matrix{ ... } where ... contains braces.
|
||
;; Support AmS-TeX's \{d,t,}frac, \{d,t,}binom notations.
|
||
;; Format and parse sums and products in Eqn and Math modes.
|
||
;;
|
||
;; Get math-read-big-expr to read sums, products, etc.
|
||
;; Change calc-grab-region to use math-read-big-expr.
|
||
;; Have a way to define functions using := in Embedded Mode.
|
||
;;
|
||
;; Support polar plotting with GNUPLOT.
|
||
;; Make a calc-graph-histogram function.
|
||
;;
|
||
;; Replace hokey formulas for complex functions with formulas designed
|
||
;; to minimize roundoff while maintaining the proper branch cuts.
|
||
;; Test accuracy of advanced math functions over whole complex plane.
|
||
;; Extend Bessel functions to provide arbitrary precision.
|
||
;; Extend advanced math functions to handle error forms and intervals.
|
||
;; Provide a better implementation for math-sin-cos-raw.
|
||
;; Provide a better implementation for math-hypot.
|
||
;; Provide a better implementation for math-make-frac.
|
||
;; Provide a better implementation for calcFunc-prfac.
|
||
;; Provide a better implementation for calcFunc-factor.
|
||
;;
|
||
;; Provide more examples in the tutorial section of the manual.
|
||
;; Cover in the tutorial: simplification modes, declarations,
|
||
;; bitwise stuff, selections, matrix mapping, financial functions.
|
||
;; Provide more Lisp programming examples in the manual.
|
||
;; Finish the Internals section of the manual (and bring it up to date).
|
||
;;
|
||
;; Tim suggests adding spreadsheet-like features.
|
||
;; Implement language modes for Gnuplot, Lisp, Ada, APL, ...?
|
||
;;
|
||
;; For atan series, if x > tan(pi/12) (about 0.268) reduce using the identity
|
||
;; atan(x) = atan((x * sqrt(3) - 1) / (sqrt(3) + x)) + pi/6.
|
||
;;
|
||
;; A better integration algorithm:
|
||
;; Use breadth-first instead of depth-first search, as follows:
|
||
;; The integral cache allows unfinished integrals in symbolic notation
|
||
;; on the righthand side. An entry with no unfinished integrals on the
|
||
;; RHS is "complete"; references to it elsewhere are replaced by the
|
||
;; integrated value. More than one cache entry for the same integral
|
||
;; may exist, though if one becomes complete, the others may be deleted.
|
||
;; The integrator works by using every applicable rule (such as
|
||
;; substitution, parts, linearity, etc.) to generate possible righthand
|
||
;; sides, all of which are entered into the cache. Now, as long as the
|
||
;; target integral is not complete (and the time limit has not run out)
|
||
;; choose an incomplete integral from the cache and, for every integral
|
||
;; appearing in its RHS's, add those integrals to the cache using the
|
||
;; same substitution, parts, etc. rules. The cache should be organized
|
||
;; as a priority queue, choosing the "simplest" incomplete integral at
|
||
;; each step, or choosing randomly among equally simple integrals.
|
||
;; Simplicity equals small size, and few steps removed from the original
|
||
;; target integral. Note that when the integrator finishes, incomplete
|
||
;; integrals can be left in the cache, so the algorithm can start where
|
||
;; it left off if another similar integral is later requested.
|
||
;; Breadth-first search would avoid the nagging problem of, e.g., whether
|
||
;; to use parts or substitution first, and which decomposition is best.
|
||
;; All are tried, and any path that diverges will quickly be put on the
|
||
;; back burner by the priority queue.
|
||
;; Note: Probably a good idea to call math-simplify-extended before
|
||
;; measuring a formula's simplicity.

This is nil (the default) if the Gregorian calendar is the only one used.

Otherwise, it should be a list `(YEAR MONTH DAY)' when Calc begins to use
|
||
the Gregorian calendar; Calc will use the Julian calendar for earlier dates.
|
||
The dates in which different regions of the world began to use the
|
||
Gregorian calendar vary quite a bit, even within a single country.
|
||
If you want Calc's date forms to switch between the Julian and
|
||
Gregorian calendar, you can specify the date or choose from several
|
||
common choices. Some of these choices should be taken with a grain
|
||
of salt; for example different parts of France changed calendars at
|
||
different times, and Sweden's change to the Gregorian calendar was
|
||
complicated. Also, the boundaries of the countries were different at
|
||
the times of the calendar changes than they are now.
|
||
The Vatican decided that the Gregorian calendar should take effect
|
||
on 15 October 1582 (Gregorian), and many Catholic countries made
|
||
the change then. Great Britain and its colonies had the Gregorian
|
||
calendar take effect on 14 September 1752 (Gregorian); this includes

the United States."
