THANK YOU! When I was trying to learn matrices, I struggled so hard because nobody ever offered a practical example of what they can be used for... my prof and curriculum just jumped into the empty motions of completing math problems involving matrices, but never clarified how they would be used beyond passing a math class. I knew if I could just get a clear example like this, I could make more sense of what I was doing, which is the only way it sticks in my mind.

This example of the network nodes and paths to build a starting matrix is very good, and thank you for being the first one to provide an example of how in a practical manner it is applied.

Was studyin this fr 3 years, tday i knew whr it is used😂

Excellent explanation. No one has ever taught mathematics like that

Thanks for the clear explanation using a practical example. It helps to understand why are we using matrices and why they are useful

So can matrices be identified by letters too?

@apel1752 8 ай бұрын

sir, then what's the difference between Matrix and Algorithm? in terms of the same example you're using..

@MathPartner 8 ай бұрын

These are completely different things so it very difficult to compare in the way that you request (i.e., identifying their differences). An algorithm is a set of rigorous instructions that allows a process to be carried out. A matrix is a table of elements where the rows and columns have some particular relationship to each other. In the example given in the video, the matrix formed is the set of weighted and directed connections between the nodes A, B, and C. From here we may choose to perform some operations such as finding the inverse, eigenvectors and eigenvalues, the degree and path centrality, or walks, cliques and subgraphs. The operations used to find each of these could be described as algorithms.

This does not explain why matrix multiplication is defined the way it is

Probably a good lecture, but do you have an other video version of it, where all the questions "OK?" after each sentence are muted?

You compiled a table or array of numbers, you didn't create a matrix. There was no mention of the numbers representing the coefficients of an equation.

The example in this video forms a weighted adjacency matrix of a graph. You have mentioned another application of matrices which is to form a matrix representation of a system of equations, which includes a coefficient matrix. This is a different example to that given in this video. Matrices can arise in many other situations, too. The aim of this video was to show one simplified, real-life example.
