Math Minion 2.2.5
Device: Mac OS
Category: Utilities
Price: Free, Version: 2.2.4 -> 2.2.5 (iTunes)

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, matrix inversion, comparison functions, an interpolation function and more. • a flexible unit conversion system that helps automate dimensional analysis models and model arrays for information and calculation encapsulation • a solver for one or more nonlinear equations • an optimizer • an ordinary differential equation solver • a x-y graph tool. • an iterator tool. • Supports iCloud document handling compatible with the Math Minion on iOS.
What's New
Resolved some minor issues:• Improved the checking for unit mismatches in the matrix object.• Changed ODE so auto run is on by default. This is likely to reduce confusion since previous values are otherwise retained (including their units) until the reset button is pressed.• When an input expression for a sub model was viewed in the context of the parent model, the object browser would incorrectly show the objects in the parent's parent.• Added ug (micro gram) to the standard unit list.• Now check for a possible conflict when creating iCloud sessions and the names only have case differences.• Changes to reduce the number of missing object messages that occur when a formula has a reference to a non-existent object.
