mathjs - npm Package Versions
Changelog
2013-07-23, version 0.11.0
- Changed math.js from one-based to zero-based indexes.
- Getting and setting matrix subset is now zero-based.
- The dimension argument in function
concatis now zero-based.
- Improvements in the string output of function help.
- Added constants
trueandfalse. - Added constructor function
boolean. - Fixed function
selectnot accepting0as input. Thanks Elijah Manor (@elijahmanor). - Parser now supports multiple unary minus operators after each other.
- Fixed not accepting empty matrices like
[[], []]. - Some fixes in the end user documentation.
Changelog
2013-07-08, version 0.10.0
- For complex calculations, all functions now automatically replace results
having an imaginary part of zero with a Number. (
2i * 2inow returns a Number-4instead of a Complex-4 + 0i). - Implemented support for injecting custom node handlers in the parser. Can be used for example to implement a node handler for plotting a graph.
- Implemented end user documentation and a new
helpfunction. - Functions
sizeandsqueezenow return a Matrix instead of an Array as output on Matrix input. - Added a constant tau (2 * pi). Thanks Zak Zibrat (@palimpsests).
- Renamed function
unaryminustounary. - Fixed a bug in determining node dependencies in function assignments.
Changelog
2013-06-14, version 0.9.1
- Implemented element-wise functions and operators:
emultiply(x .* y),edivide(x ./ y),epow(x .^ y). - Added constants
InfinityandNaN. - Removed support for Workspace to keep the library focused on its core task.
- Fixed a bug in the Complex constructor, not accepting NaN values.
- Fixed division by zero in case of pure complex values.
- Fixed a bug in function multiply multiplying a pure complex value with Infinity.
Changelog
2013-05-29, version 0.9.0
- Implemented function
math.parse(expr [,scope]). Optional parameter scope can be a plain JavaScript Object containing variables. - Extended function
math.expr(expr [, scope])with an additional parameterscope, similar toparse. Example:math.eval('x^a', {x:3, a:2});. - Implemented function
subset, to get or set a subset from a matrix, string, or other data types. - Implemented construction functions number and string (mainly useful inside the parser).
- Improved function
det. Thanks Bryan Cuccioli (@bcuccioli). - Moved the parse code from prototype math.expr.Parser to function math.parse, simplified Parser a little bit.
- Strongly simplified the code of Scope and Workspace.
- Fixed function mod for negative numerators, and added error messages in case of wrong input.
Changelog
2013-05-18, version 0.8.2
- Extended the import function and some other minor improvements.
- Fixed a bug in merging one dimensional vectors into a matrix.
- Fixed a bug in function subtract, when subtracting a complex number from a real number.
Changelog
2013-05-10, version 0.8.0
- Implemented a command line interface. When math.js is installed globally via npm, the application is available on your system as 'mathjs'.
- Implemented
endkeyword for index operator, and added support for implicit start and end (expressions likea(2,:)andb(2:end,3:end-1)are supported now). - Function math.eval is more flexible now: it supports variables and multi-line expressions.
- Removed the read-only option from Parser and Scope.
- Fixed non-working unequal operator != in the parser.
- Fixed a bug in resizing matrices when replacing a subset.
- Fixed a bug in updating a subset of a non-existing variable.
- Minor bug fixes.
Changelog
2013-05-04, version 0.7.2
- Fixed method unequal, which was checking for equality instead of inequality. Thanks @FJS2.
Changelog
2013-04-27, version 0.7.1
- Improvements in the parser:
- Added support for chained arguments.
- Added support for chained variable assignments.
- Added a function remove(name) to remove a variable from the parsers scope.
- Renamed nodes for more consistency and to resolve naming conflicts.
- Improved stringification of an expression tree.
- Some simplifications in the code.
- Minor bug fixes.
- Fixed a bug in the parser, returning NaN instead of throwing an error for a
number with multiple decimal separators like
2.3.4. - Fixed a bug in Workspace.insertAfter.
- Fixed: math.js now works on IE 6-8 too.
