Calculator Tab


This tab contain a list of entered expressions or scripts. You can reselect and edit for different results. You can create variables for subsequent calculations displayed in the right column.

Scripts Tab


This tab contains a collection of scripts containing a sequence of calculations including debugging capabilities. The right column allows easy access to saved scripts for editing and running.

Graphs Tab


This tab contains a collection of graphs created by running a script to produce data points used for plotting. The right column allows easy access to view resultant graphs.

Notes Tab


This tab contains a collection of notes for general purpose documentation.

Outputs Tab


This tab displays output from expressions entered in the Calculator tab to calculate it's value. Also, it contains resultant outputs from script's execution.

Features

Graphing
Display 2D and 3D plots containing single to multiple lines, scatters, bar, candlesticks, polar, spider, jitter, vector fields, surfaces, and contours charts including controls for colors and styles, as well free-form drawing simulations.

Linear Algebra
Standard matrix operations consisting of arithmetic operators, invert, transpose, determinant, diagonal, cross, dot, and other operations.

Statistics
Collection of statistical functions consisting of Chi Squared, Fisher's F, Gamma, Normal, Student's T, Uniform, and many more.

Financial
Basic financial functions consisting of periodic payments, interest payments, principal payments, and future value.

Miscellaneous
