CalcEn is a comprehensive complex number calculator with a simple interface that includes a nice natural display for editting and computing complex mathematical expressions matrices and polynomial functions.

A few of the special features that are unique to CalcEn include the following:

- Solves complex math problems by taking a picture

- Natural display for editting mathematical expressions

- Complex Functions - functions that accept complex arguments

- Computation on the Complex plane

- Logarithmic functions can accept arguments less than zero.

- More functions to work with - csc sec sgn and much more

- Hyperbolic functions and their inverses

- Complex numbers can be written in rectangular or polar form.

- Complex results can be converted between polar and rectangular forms.

- Calculations can be done in radians(RAD) or degrees(DEG).

- A nice interface to display history of previous calculations

- Results can be formatted to a desired number of significant digits

- Complex matrices

- Element-wise and Matrix operations

- Simplification of functions with real or complex coeffcients

- Roots of real or complex functions can be computed
