~~~~~~~~~ Check out our FREE app Console, which is powered by SIMO's MATLAB interpreter. If you find Console useful, SIMO is definitely suitable for you. ~~~~~~~~~ SIMO is a feature-rich development environment for MATLAB. We have developed a version of MATLAB interpreter that works for commonly used language syntax and functions for beginners. [+] Who will find SIMO useful? - Students learning the basics of MATLAB. - Course instructors of fundamental MATLAB courses. - Individuals whose works do not depend on specialised toolboxes and advanced language syntax. [+] What is SIMO? - It is an integrated environment for running MATLAB. - It allows you to create, edit, and run MATLAB code on iOS devices. - Unlike other apps that compute on the cloud, it performs computation entirely locally on device. No internet connection is needed. You don't miss a single app feature even if you are offline. [+] What SIMO cannot do? - It does not completely replace MATLAB, as it has only a subset of built-in functions of MATLAB. - It does not support advanced features such as Simulink or creating user-interface. [+] One app, all platforms - You will be amazed at how much work you can do on a phone. The app is designed to let you work effectively on smaller screens. - The iPad app features a split-screen layout. You can enjoy a full-screen workspace, or work on two views simultaneously. - The iPad app runs on Macs with Apple silicon as well. Buy one app and it works on all of the platforms. [+] MATLAB interpreter - The interpreter works for language syntax that is essential to survive a MATLAB course. It provides the most commonly used built-in functions for learners. - The interpreter computes on your device locally. You will not miss a single app feature even if you go completely offline. - SIMO comes with a full set of documentation and user guides. It is offline accessible and full-text searchable. [+] Visualization tool - Plots are rendered in real-time using your device's computing power. Operations such as updating line attributes, pan and zoom are fast and responsive. - Stunning 3D plots are rendered by the device's GPU in real-time. Pan, zoom or rotate with multi-touch gestures, trackpad or keyboard shortcuts. - Plot attributes are editable through the built-in user-interface. You can improvise with different styles without entering a single line of code. [+] Command console - You can run one or many lines of code from the command console. It supports line numbering, auto-intent and syntax highlighting. - Search over thousand lines of output data instantly. You'll never get overwhelmed by the sea of numbers. - Output data are formatted automatically to fit the screen size or app window. Data are always neatly presented however you resize the app. [+] File manager - Files can be synced across all of your iCloud Drive enabled devices (iPhone, iPad, Mac).

Finding the symbol you want to use in LaTeX can be hard since you can't memorize all the commands and packages for every symbol. DeTeXt tries to solve this problem by giving you two ways to find the command you want: - Draw the symbol you want and DeTeXt's neural image classification engine will identify what it thinks are the 20 most likely LaTeX commands that will generate a symbol closest to the one you drew. DeTeXt supports Apple Pencil drawings on the iPad. - Search the entire symbol set of 1098 symbols from packages like tipa, amsmath, amssymb, textcomp and more, in addition to the default mathematical symbols. - Copy the symbol, or the character itself, or its Unicode codepoint to the system clipboard, to paste anywhere else. DeTeXt's neural engine processes your drawn symbol and finds the best matches in its symbol database, all on your device without requiring you to be online. All the symbols are stored within the app as well.
