iMath - 2.1.4
This Release Brings A Multitude Of Small Features And Bug Fixes
The GUI was improved, and new keywords were introduced: Table cells and Calc cells can now be referenced in an iFormula, Matrix handling was improved, ...
- Add option to suppress units when printing formulas
- Added option to control evaluation of nth roots for negative bases to real values or principal branch values.
- Integrated realroots option, inhibit underflow option and suppress units option into the dialogs and the documentation.
- Allow multiple letters and digits in subscripts without curly braces
- Enable implicit multiplications before and after formula labels
- Enable unicode parsing of chart names, labels, etc.
- Add function det() to calculate the determinant of a matrix
- Add keyword TEXTFIELD to set variables from text fields
- Fix bug that prevented a symbol from being changed to a vector or matrix after the first calculation run
- Add keywords TABLECELL and SETTABLECELL to get and set the value of a cell in a writer table
- Add keywords CALCCELL and SETCALCCELLS to get and set the value of a calc document cell range
- Master documents: If the master document is already loaded, don't reload it
- Complete rework of matrix handling
- Put the debug output file into the user's temporary directory on Windows
- Fixed bugs in connection with the factorial function
- Fixed bug that did not recognize iFormulas after a copy-and-paste action
- Fix problem with flickering charts in Windows
- Extend QUO and REM to numeric arguments
- Add AND, OR and NEG keywords (these are only interpreted within the first argument to the ifelse() function)
- Ensure that a forced recalculation really does recalculate everything
- Improve the Create_iFormula dialog
- Show a field for compile error messages in the Create_iFormula dialog
- Fix bug that did not allow using a unary minus on an equation
- Allow iMath to distinguish between expression lists, e.g. x;y;z , and vectors, e.g. (x;y;z). Vector must be enclosed in brackets
- Allow finishing the Edit iFormula dialog by pressing enter in the formula text window
- Add keywords REALVARDEF and POSVARDEF to define symbols as real-valued and positive. This means that e.g. the conjugate() and abs() functions can be evaluated immediately
- Add option showlabels that displays the equation label with the equation
- Show a welcome screen before the recalculation
- Changed behaviour of formula merge: Two formulas are always merged with automatic newline, and a formula followed by an expression with an automatic equal sign
- Added function charpoly to calculate characteristic polynomial of a matrix
