"Scilab for Beginners" takes a little bit more than 1 hour to introduce you to the main feature of Scilab: Matrices, Vectors and Scalars computation.
The videos include many Scilab sessions to demonstrate the matrices, vectors and scalars definition and manipulation.
The "basic" operations introduced here are not so basis, as they are globally managed matrices, vectors and scalars manipulation.
The addition and subtraction are intuive, as they are element by element operations. But the multiplication is the matricial global one, and you have to know a littke bit of linear algebra to understand it. The exponent and even matrices division are also introduced in that course.
By the end of the course, you will be able to use Scilab as a high level caculator. You will be also ready to use Scilab as a laboratoty in our forthcoming series of courses in practical mathematics.
This is an introductary course. It explains what the course is intended to teach, what is the audience and what is the goal of the course.
This Lecture explains how to get Scilab and how to install it on a Linux, Windows or Mac OS computer.
This lecture shows a complete example that uses Scilab to solve an equation with a Newton Algorithm.
And now, we make an overview of the core of the course: Matrices, Vectors and Scalars definition and global manipulation.
This Lecture explains that the variables in Scilab are typed as matrices, vectors and scalars of
real and complex numbers, booleans, and strings.
This lecture deals with "basic" operations that are the simpler matrices, vectors and scalar global manipulation. The operators are the addition and subtraction, and the boolean operations. They are defined globally as element by element corresponding operation.
This lecture shows the matrices, vectors and scalars multiplications. There exists two kinds of such multiplications, the globel multiplication and the element by element multiplication. Both are managed by Scilab.
Exponent related topics are all the ways to put to the power globally or element by element the matrices, vectors and scalars.
The divisions of matrices, vectors and scalars are left and right global division, as well as element by element division. This Lecture shows them all.
And now, it's time to say Good Bye… and see you on Mathedu website!
Fabienne Chaplais is 57, and lives in Paris, France.
She is married and has three children.
She obtained the French highest degree to teach mathematics at undergraduate level. This means that she is very accurate in mathematics and in teaching them to anyone from the beginners to the undergraduate level.
She then turned to an Engineer’s career for about 30 years.
She became an expert in R&D, especially when using applied mathematics and scientific programming in high level languages such as Matlab and Scilab.
She notably worked on satellites guidance, shuttle accosting and reentry .She applied her exoertise to implementing various complex algorithms such as Kalman filters and fuzzy logic.
After that, she worked in the railway industry, on automatic urban transportation systems for Paris and New York. After various R&D projects including error correcting Viterbi encoding and decoding as well as formal method based B language, she became an expert in safety analysis involving many specialized sharp inductive and deductive approach, including probability calculations.
She then founded Mathedu with her husband, a Researcher in Control Science.
Mathedu aims to teach mathematics from a practical point of view.
The idea is to let the students be in action with a very pragmatic approach, using its computer with Scilab installed as a laboratory.
Then and only then, the link with theory is done, in a very progressive way.
Learning maths with us will let you find the subject easy, so that you will no more understand why mathematics were so hard to understand before…
