ZCalcLab 4+

This performs arithmetic operations to complex math, matrices, & statistical computation with conditional & looping scripting controls with 2D & 3D plotting capabilities.

• Plotting: Display 2D and 3D plots from single to multiple lines, scatters, bar charts, and many more special plots including controls of colors and styles.
• Drawing: Display drawings of dots, lines-n-curves, squares-n-circles, polygons, and text including buttons, switches, sliders, selections, and text fields controls for display simulations.
• Scripting: Write your own functions in the scripting language that can be organized into a collection of projects (i.e., libraries) for easy accessibility.
• 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.
• Special: Collection of special functions consisting of Bessel, Gamma, Legendre, and many more.
• Units: Unit conversion of linear, time, temperature, and many more.
• Financial: Collection of basic financial functions consisting of periodic payments, interest payments, principal payments, and future values.
• Documentation: Quick tour of the app including built-in of all functions with numerous examples to get you started quickly.
• Miscellaneous: Custom keyboard designed for entering arithmetic expression to calculate.
• WiFi/Cell: Unlike other similar apps, this requires no internet connection or cellular data to evaluate your expressions or running your scripts.
