It can create x-y plots with the plot function, contour plots with the contour function, 3D plots with the surf function, histograms with the histplot function and many other types of plots. Scilab can produce many types of 2D and 3D plots. What kind of plots can you make with Scilab? nz the level values or the number of levels.z is a real matrix of size (n1,n2), containing the values of the function or a Scilab function which defines the surface z=f (x,y),.What are the values of X and Y in Scilab? The myquadratic function takes two input arguments x1 and x2 and returns f (x1,x2) = x1^2 + x2^2. In the following Scilab session, we use a simple form of the contour function, where the function myquadratic is passed as an input argument. ![]() ![]() How to calculate the number of levels in Scilab? The transpose command works for matrices as well: –>P’ ans = 1. answer is 2, 3 We can assign these values to variables as follows: –> = size(P) col = 3. The size of a matrix can be obtained by using the size command –>size(P) ans = 2. We can find the length of a vector as follows: –>length(p) ans = 3. This can be done in two ways: first one is using spaces –>p = p = 1. ![]() To practice this tutorial, you need to have Scilab installed on your system. How to find the length of a vector in Scilab? powered by SCILAB AS A CALCULATOR The purpose of this tutorial is to get started using Scilab as a basic calculator by discovering some predefined data types and functions. The purpose of this tutorial is to get started using Scilab as a basic calculator by discovering some predefined data types and functions. The same technique applies if we want to extract a column. This way the code is more simple, compact and robust. –> If we are interested in all the elements of the columns for a particular row it makes sense to use the colon operator because we don’t have to specify the index for the first and last column. When to use colon or colon operator in Scilab?ġ3. Basically this tells Scilab to extract the values from all the columns corresponding to the second row: –>testRow = testMatrix (2,:) testRow = 11. To do this, as arguments of the matrix we insert the row index, followed by the colon operator. How to extract values from second row in Scilab? First let’s define a matrix which is going to be our test variable. In this article we’ll learn how to extract a particular value from a matrix or a particular set of values (e.g. So far we have learned how to define a matrix in Scilab. Since we know that we have 4 columns, we tell Scilab to extract the values starting with the 1st column up to the 4th column, corresponding to the 2nd row: How to extract data from a matrix in Scilab? Which is the correct way to extract columns in Scilab?Īnother method of doing the same extraction is using the explicit definition of the start and end column index. 4 2.4 The variable browser and the command history. The first way is to use Scilab interactively, by typing commands in the console, analyzing the results and continuing this process 2 2.2 The editor. What are the first steps in using Scilab?įirst steps. A matrix of all ones can be created with ones command as follows –>ones(2,4) ans = 1. Using Scilab we can create special matrices: For example we can create a matrix of zeros with 3 rows and 4 columns using this command –>zeros(3,4) ans = 0. How to create a special matrix in Scilab?
