~~~~~~~~~ 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). Or, you can store them locally on device. - Tons of files buried in tons of folders? No worries. The search feature will help you find an item instantly. - It has features you expect from a useful file manager. Add, copy, delete, duplicate, move, rename, sort and more. [+] Script editor - It has features you expect from a useful script editor. Syntax highlight, auto-indent, line numbers and more. - Search for a word in a script. Replace occurrences with another word. - Recent items are accessible from your finger tip. It is a useful feature for navigating through frequently accessed files.
