I think these are the Scilab operators that you’ll use in your applications. The logical operators can be used in order to test several conditions in the same time: ->temperature = rand()*100 The logical operators are mostly used within conditional loop like: if, while, etc. In order to perform logical operation in Scilab we can use AND, OR and NOT operators. The comparison operators can be applied also to matrices, strings or complex numbers: ->= The output of a comparison will be a variable of type Boolean: ->32 > 17 With these operators you can make the following comparisons: smaller, greater, smaller or equal, greater or equal, equal, not equal. In order to compare two or more variables between them, Scilab uses the relational operators. Relational (comparison) operators in Scilab The table below contains examples for all dot operation applied to matrices: Operator In the above example each member of the left matrix was multiplied with the corresponding member of the right matrix. Special matrix arithmetic operations in ScilabĪ normal matrix multiplication, using the star operator “*”, is done in the following manner:Ī_įor example, for matrix multiplication if you use the dot operator you’ll get the following result: ->.* Also, Scilab sets priorities regarding the calculation order. Except exponentiation, all mathematical operations can be applied to scalars, vectors and matrices. Within Scilab we can perform: additions, subtractions, multiplications, left and right divisions and exponentiation. For example, the Hilbert matrix is symetric positive definite. For some of these test matrices, the exact eigenvalues, condition number or invert is known. Rectangle: it won't work because it has to follow the rule of matrix. These test matrices can also be used to experiment with linear algebra algorithms, such as the resolution of systems of linear equations or the eigenvalue problem. it raises each element individually (see Scilab help). From the operators point of view, Scilab is able to fulfil arithmetic calculations, comparison and logical operations. It has different behaviors if input a is a vector (1-by-n or n-by-1 matrix), rectangle matrix (m-by-n matrix, m n ), or square matrix (n-by-n matrix): Vector: it works like. Scilab is capable of simple mathematical calculation as well as complex calculations.
