Things get more complex when we combine rotation, translation and scale matrices.

Max. vertex blend matrices

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.

Given two matrices like these,

It is complex. Space is complex.

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.

Very complex processes with very complex chemicals that fit into very complex receptors.

Lying's complex.

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.

These are complex things built with complex parts that come together in complex ways.

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.

It's immensely complex.

It's immensely complex.

Running Kolzer complex.

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.

For anything more complex, you should use the complex syntax.

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

An Assistant dialog to simplify inverting of 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.

This isn 't called complex because the syntax is complex, but because you can include complex expressions this way.

How complex is it?

Lots of complex stuff.

These are complex issues.

Our emotions are complex.

So everything but complex.

It's inside the complex.
