Your project needs a laser sharp focus for you to achieve something really useful. The modules will help you learn the more intricate details of your narrow area. When you get advanced, read the documentation for the modules you need and use their built-in functions. You can also have variables inside the script that are local to the routine. When you have identified the area of interest you can find most functions for your particular area of interest. Scilab already includes many mathematical constants like pi, squareroot and trigonometric functions.
The top has comments, denoted by stars at the beginning of the row. This is a deliberate choice from the designers.
The ‘m’ denotes matrix the regular sin handles single numbers also, this is the same for most available functions.įor people with some experience scripting, the octave language will look familiar in many ways. Another important thing to note is that the procedure uses sinm, with an ‘m’ at the end. You can use it to prototype small functions for bigger pieces of software, it can also be used to find solutions quickly to questions that pop up during work. Without the semicolon the value would just show up in an answer on the line below and all information is lost. Look carefully at the first statement, it ends with a semicolon. In the above expression, the routine sets A as a matrix and the values are used in the calculation. On the console, type in your expression and the result will appear below. To see what is available, the best is to try out some calculations with the console. You will see the executing code in the console and the result in a separate graph window. This part of Scilab can consume hours for the math geek but make sure you start coding with the help of these demos. The module ‘graphplot’ shows this in illustration 1: For example, you can see samples of the different color themes available for graphs. What pops up is a long list of demonstration scripts to show you what you can use the software for. If this is the first time you use scilab, start the demostrations from ‘?→ Scilab Demonstrations’ menu. This includes a USB library and Arduino support. Some add mathematical capabilities for specific applications while others add communication capabilities. In there is a large collection of modules. To do this, open the module manager from the Application menu.
The other way to install new packages is to search with the built-in function of the application. You can both run and copy the code into an empty file and change for your own functions.
The documentation also shows up in the help browser, the best way to get to know the package is to use the code in the documentation. When you start scilab next time, celestlab will be available in the Toolboxes menu.
