# Eigenmath DS 1.1 version
## Introduction
The aim of this project is to have a portable free CAS comparable to commercial
systems such as Texas Instruments or HP calculators.
Download the latest version [here](https://github.com/AntonioND/eigenmathds).
## Instructions
- Terminal output mode:
- A: Eval math sentences.
- B: Swap otput window to graph window and back.
- Y: Swap otput window to edit script window and back, when button Y is
pressed again, the sentences in script window are ready to use in the otput
mode.
- X: Flip screens
- START: Text zoom is raised. Press again to back to normal font size.
- Up: Scroll up otput window.
- Down: Scroll down otput window.
- Left: Previous history commands.
- Right: Next history commands.
- Script edit mode:
- Up, Down, Left, Right: Move cursor.
## Recommendations
If the results are too big to display in normal font size, press START or try
the tty terminal mode.
For a large formula or a big matrix use the script mode, is less tedious correct
the values.
The command clear clears all previous operations, asignations, results and it
clears the graph area except for the script mode.
There are two ways to use draw button:
draw(sin(x))
enter
or
sin(x)
draw
enter
Remember there are special funtions for matrix operations: `dot`, `inv`...
## Build
Install [BlocksDS](https://blocksds.skylyrac.net/docs/).
