Math Minion

       Mac OS

Depending on your needs, Math Minion can be either a powerful scientific calculator that understands units, or a sophisticated modelling tool that is better suited to science and engineering problems than traditional spreadsheet programs.

It combines a mind map style representation of the relationships between expressions, with a formula system that operates transparently on scalars, arrays and matrices. A hierarchical model system helps encapsulate calculations in logical and easily duplicated units and a flexible unit conversion system tracks the fundamental property types through calculations. This allows it to know, for instance, that some fathoms divided by a few days is in fact a velocity that should not be added to a kilogram.

Some interesting features include:

• equations that work equally well with scalars, arrays and matrices

• a function library that in addition to the usual suspects includes:
- matrix multiplication, inversion, eigenvalues, eigenvectors, transpose and redimensioning
- comparison (eq, ne, lt, ge, if etc)
- string functions (split, join, regular expressions, etc.)
- interpolation, indexof, select
- complex number and statistical functions
- time, sorting, random, web reading and many more

• an innovative unit conversion system with automatic dimensional analysis

• data tables for storing and manipulating tabular data whether numeric or string

• models and model arrays for information and calculation encapsulation

• a solver for one or more nonlinear equations

• an optimizer

• an ordinary differential equation solver

• an iterator tool.

• 2D and 3D graphs.

• HTML forms.

• share sessions between iOS and Mac devices using iCloud

• Can store and retrieve sessions from Dropbox

What's new

• The font size for the expanded formula editor, notes, string, report preview and help views can now be increased or decreased.

• The range operator ":" can now have the first argument larger than the second and will produce a decreasing range.
