Downloads

By downloading ScienceSuit you acknowledge that you have read and accepted the terms of the license agreement.

NOTES:

• On Windows 10, unzip the downloaded file and run sciencesuit.exe to run the software.
• ScienceSuit best works on Windows 10 with a resolution of 1920x1080.
• On high DPI screens you might want to Override Default Scaling Settings (in most cases selecting Application works well) for better visuals.

VERSION 1.7.5

NEW & IMPROVED

• cumtrapz accepts a variety of combinations of function and vector.
• Faster implementations of trapz, linspace, accumulate, var functions.
• median function now works with all types of iteratable containers.
• Prettier printing of Vector and Matrix at command-line.
• sample function supports named-argument call {x=, size=, replace=true}

CHANGES

• cumsum now only accepts Vector data type.
• Type member function for Workbook and Worksheet discontinued as they are not needed any longer. If wb and ws are of type Workbook and Worksheet respectively, type(wb) or type(ws) will still return the correct types.

BUGS

• eye was not reporting the identity matrix correctly. This has been fixed.
• Regardless of the number of open Workbooks, getworkbooks was returning a Lua table with only single entry. This has been fixed.

VERSION 1.7.4

NEW

• dunif, punif, qunif functions for uniform distribution.
• Re-design of newton function. Depending on the arguments, either Newton-Raphson or Secant method is used.
• Re-design of bisection function. False Position and Modified False Position methods have been included.
• title member function for Workbook

CHANGES

• Database data structure sql member function now returns a 2D or a 1D Lua table depending on the outcome of the SQL query. Previously, a 2D table was always returned.
• Previously bisection and newton functions only returned root and error. Now they return root, error and number of iterations.
• The key func in the function newton has been changed as f.
• Workbook member functions ID and count return numbers as integers rather than as floats.
• Workbook member functions open and save have the option not to provide full paths anymore.
• Thermodynamic Properties of Fluid App starts with the default fluid type as water. Previously, no fluid type was initially selected.

VERSION 1.7.3

NEW

• F-test app
• test_f function

IMPROVEMENTS

• Internal lexical analyzer which is used in std.tokenize and also in command editor is more stable.

• The function ttest has been renamed as test_t.

BUGS

• When more than 2 rows or columns to be deleted, an error message popped up. This has been fixed.
• t-test apps reported p-values as "p-value two tail". The wording "two tail" has been removed as p-value is calculated depending on the choice of alternative.

VERSION 1.7.2

NEW

• Paired t-test app

• normalize() member function for Food data structure.

• When adding apps to ribbon page via a dropdown menu, each entry in the menu now accepts image (32x32)

CHANGES

• The tag RIBBONPAGE (used in manifest.xml file) is renamed as PAGE.

• Food data structure: The user-provided functions to calculate specific properties (k, cp, aw, pH) now sets the internal value and therefore persists throughout the variable's life.

BUG FIXES

• Error reported by linest function is fixed.

• When a range that does not contain numeric values was selected, the calculations reported an error. This was fixed.

• "Copy as Image" function of Workbook works stable.

VERSION 1.7.1

• Regardless of the size of the output, command-line precisely scrolls the view to the location of the input line.
• insert member function of Matrix now accepts Lua tables as well. A new member function, namely append, is also added to Matrix data structure.
• The framework and apps should run without any problems on Windows 10 machines.

VERSION 1.7

• Significant improvements in terms of usability and performance.
• Many new functions, especially for statistical distributions, algorithms and utilities.
• Command editor now supports code completion.
• A brand-new significantly more usable script editor.
• The concept of Iteratable containers (Vector, Matrix, Range, Array) supports pairs and next.
• Vector, Matrix, Array and Worksheet support indexed element access for considerably better-readable code.
  • v[1]=3 or m[1][1]=2 instead of v:set(1,3) and m:set(1,1,2), respectively.
• All of the existing apps have been improved and new apps have been introduced.
• wxLua has been discontinued, rather IUP framework has been adopted for developing apps with Lua.
• Lua engine has been upgraded to Lua 5.3.

VERSION 1.6

• Introducing Undo/Redo support for Workbook to significantly improve convenience of data manipulation.
• Worksheets now can be dragged to a new location on the Workbook.
• Several enhancements for usability.
• GUI of Psychrometry app has been improved.
• Bug fixes, notably for the paste function, image area statistics at different zoom levels and Range object access when Worksheet goes out of scope.

VERSION 1.5

• Easier to use graphical user interface, especially for Workbook and Scripts.
• Introduction of Copy As & Paste As features.
• Bug fixes for ribbon buttons and history file.

VERSION 1.4

• Introduction of the standard library, std. Except inherent Lua functions, all functions are now under the std library.

• New settings menu for Script Editor to control the style of scripts. The styles are synched with copy and export as HTML functions.

Info for geeks:

• Lua internal engine has been upgraded to Lua 5.2.4:

  • Better integration with Lua's garbage collection.
  • No need to use destroy member function for Matrix, Vector and Array classes, therefore the member function destroy in these classes is discontinued.

CHANGES

• New functions: dbinom, dnorm, dpois, pbinom, pnorm, ppois, rbinom, rnorm and rpois.

• Re-designed functions: rand, runif and eig.

• The function tomatrix is discontinued.

BUG FIXES

• Command-line: When there was an assignment operation, the interactive commandline was not printing the errors which were thrown not due to syntax errors but from the functions which were executed during assignment, such as due to incorrect arguments. This has been fixed.

• rand or runif: If called in a loop, rand() or runif() was producing exactly the same sequence for a vector or matrix, this has been fixed such that a piece of code t={}; for i=1,5 do t[i]=rand(10) end will produce 5 vectors each containing a sequence with different random numbers.

• eig: Although the matrix was square, an error was reported as to matrix not being square. This has been corrected.

• Matrix: The subtraction operator for Matrix is now supported.

INFO FOR NERDS

• Due to performance hits with MSVC, the Eigen library has been downgraded to 3.2.10 to increase performance of functions such as eig.

  • Lua tables are printed depending on whether keys are available or not.
  • psychrometry function now accepts case-insensitive keys.
  • eigv function was discontinued. eig function now works similar to eigv depending on the input parameters.

  INFO FOR NERDS

  • Boost XBoost XML was discontinued and wxWidgets XML facilities have been used. This provided significantly better integration with wxWidgets classes for managing archives.
  • TDM-GCC compiler suite and Eclipse IDE were discontinued and Visual Studio 2015 has been used for development and code production.an class="auto-style13">Boost library was updated to version 1.63.0.
