Looks like some sort of secreted resin.

You know, you load and save vectors and matrices, load and save data, put together matrices to create bigger matrices, index into or select specific elements on the matrices.

He also creates phantasmagoric sculptures made of bones from cast resin.

This thing was made of resin and it was too light.

Given two matrices like these,

Let's think about these 2 matrices.

How do you manipulate these matrices?

Can I multiply these two matrices?

Returns this matrices called magic squares.

So they only exist for square matrices. And then, sometimes, you can't even invert square matrices.

So, I went down to my shop, and I molded it and I cast it in resin, because in the resin, then, I could absolutely get the glass smooth finished.

Talk about what are matrices and vectors. Talk about how to add, subtract, multiply matrices and vectors.

So let me think of two matrices.

Now let's look at vectors and matrices.

Working with matrices that don't have inverses.

And that's how we added matrices so maybe it's a natural extension to multiply matrices the same way.

Because you know from the first video we did on matrices, that you can't add these two matrices.

Finally, by convention, usually when writing matrices and vectors, most people will use upper case to refer to matrices.

So now let's learn how to multiply matrices.

Just a couple more ways to generate matrices .

And so, what does addition of matrices mean?

Inverses only exist for certain types of matrices.

Well, what did we learn about multiplying matrices?

So you can not multiply those two matrices.

Now here are some other ways to generate matrices.

So the question is, can I multiply these matrices?

Could I have multiplied the matrices the other way?

And I tend to put brackets around my matrices.

So, here's how you multiply together the two matrices.

So, you now know what are matrices and vectors.

Matrix addition is defined if both matrices have the exact same dimensions, and these two matrices do have the exact same dimensions.

In the next video we will talk about a much more interesting step, of taking 2 matrices and multiplying 2 matrices together.

So the order in which you multiply matrices completely matters.

Next, let's talk about multiplying matrices by a scalar number.

Let's look at the inverses of some common transform matrices.

So it turns out that we can multiply two matrices.

Now, let's swap around the order of these two matrices.

X, to refer to matrices, and usually we'll use lowercase,

So, with that, hopefully you now know how to construct matrices and hopefully starts to show you some of the commands that you use to quickly put together matrices and take matrices and, you know, slam them together to form bigger matrices, and with just a few lines of code, Octave is very convenient in terms of how quickly we can assemble complex matrices and move data around.

Again these, these are matrices. Now, we wanna solve for B.

And you have also seen examples like this, square symmetric matrices.
