Scilab - another laboratory for matrices and number crunchingIt is always good to be able to work in different environments. There are several numerical tools that offer plenty of functions to work with matrices, arrays, structures and powerful visualization capabilities. This section explores some basic ideas to work with a SCIence LABoratory.
Basic Commands and Data Types We'll explore built-in functions and data types, with simple lines of code. The IF Statement The IF statement lets you evaluate a condition and works together with the THEN clause to take a course of action based on... Branching - Select Case The common Switch statement becomes the Select Case statement in Scilab, compare it with the Matlab switch case. 2D plots Basic functions to create easy 2D-plots. Functions and Scripts In past years they were called subroutines... Scilab Examples - 2D summary Several types of plots in Scilab: single and multiple plots, pies, histograms, etc. A practical approach with solutions, not only problems. Piecewise Functions See one method to create piecewise functions. See how to vectorize pieces and plot them. 3D Plots Explore some features for 3D plotting. You'll learn about parametric curves, meshgrids and other special built-in functions. Recursion in Scilab A brief experiment with the factorial function. Integral Calculator Calculate definite integrals using intg or int2d functions for this purpose. Scilab and Scicos Books Suggested books for Scilab/Scicos. Examples, applications and modeling are explored... Curve Fitting An approach to polyfit and polyval functions... Least Squares Fit An example of the leastsq function... Datafit Function Another way of curve fitting to adjust parameters... Gradient-based Optimization We use optim to accomplish minimization of functions... High-Pass filter Simulation Interface Scilab-Winspace for electronic simulations... From 'Scilab' to home From 'Scilab' to Table of Contents
