For my readers

I thought my readers will like to know the videos, in the last post, but nobody made any comment.

So, I thought my readers should choose the next subject.

I think the basic commands are well presented here.

I'd like to propose some subjects:

  • Digital image processing
  • Digital signal processing
  • Advanced Graphs
  • Advanced algebraic manipulations
Now, you choose the next post.

Videos in YouTube

I was looking my YouTube's account today, and I saw some videos that I made using Scilab.

If anyone wants to see the videos, this is my Channel in YouTube: http://www.youtube.com/alexsheep7

Following two great videos.

A simple code that shows graphs.

A more complex code that implements extended reality.

Discrete convolution properties - 2

Anyone called Younes asked something about convolution via Fourier Transform.
I made the following deduction for you Younes (click on the image for see it in the real size):

Now, I ask: try to confirm the property using Scilab.

Don't forget computers don't make infinity operations.
