LU decomposition of a matrix using sympy
In this video I show you how simple it is to do LU decomposition using sympy in python. I also show you a new way of importing sympy functions so that we do not have to use the sym abbreviation. Lastly we use a Boolean question to see whether the multiplication of the lower and upper tri

Matrices in python using sympy
In this second video on the use of sympy to do calculations in linear algebra, we take a look at the Jupyter Notebook, our coding environment in python. I also show you how to construct your first matrix, as well as a few in-built matrices such as the identity matrix. Finally, I show you

Linear Algebra for Computer Scientists. 12. Introducing the Matrix
This computer science video is one of a series of lessons about linear algebra for computer scientists. This video introduces the concept of a matrix. A matrix is a rectangular or square, two dimensional array of numbers, symbols, or expressions. A matrix is also classed a second order

How do we add matrices. A matrix is an abstract object that exists in its own right, and in this sense, it is similar to a natural number, or a complex number, or even a polynomial. Each element in a matrix has an address by way of the row in which it is and the column in which it is. Y

We have already looked at the column view of a matrix. In this video lecture I want to expand on this topic to show you that each matrix has a column space. If a matrix is part of a linear system then a linear combination of the columns creates a column space. The vector created by the

In this video, I define a cool operation called the symmetrization, which turns any matrix into a symmetric matrix. Along the way, I also explain how to show that an (abstract) linear transformation is one-to-one and onto. Finally, I show how to decompose and matrix in a nice way, sort of
