App Description

This is a Matlab-like math tool for iPhone/iPad that allow users to have as many variables/libraries as possible. You can even create your own libraries/functions to simplify your common work.

Features:

* Lua language based calculation. All benefits from Lua language such as expression/functions/libraries/condition controls are available.
* Rich sets of build-in libraries. Standard math library, matrix library, complex library, linear solving… Even more are coming!
* Custom library/function. You can create your own to make your complex calculation to only one function!
* Common Calculators with form interface, such as interest calculation and linear solver

Imaging the scenario that you want to compute the area of several circles (r = 3, 4, 5), you don’t need to type pi (3.1415926) every time:
> pi=3.1415926
> pi*3^2
28.2743334
> pi*4^2
50.2654816
> pi*5^2
78.539815

To make this more easier, we can create a function to calculate the area of circle. In library tab, create a custom library and create a new function named “area”:

function(r)
return 3.1415926*r^2 -- πrr
end

Now back to command tab and type:
> area(3)
28.2743334
> area(4)
50.2654816
> area(5)
157.07963

This tool can make your life easier!
