Video gear I use

Microphone: I use a fairly inexpensive clip-on microphone to record my videos. It is fairly crisp and is compatible with laptops and mobile phones with a 3.5mm port.

Graphic Tablet: I love this graphic tablet, it is easy to use and compact. It comes with a nice pouch as well. I also use this to create art on a free software called GNU GIMP.

Other Video gear I recommend:

Better Microphone : If you have a slightly bigger budget, then I certainly recommend the Yeti USB microphone. It’s certainly superior to the BOYA one I have mentioned above.

Pop Shield: It’s definitely also worth investing in a pop shield to get rid of pops and wind disturbances in your recording.

Light Reflector: If you don’t have the budget to invest in lighting equipment it’s worth investing in a light reflector to utilise the natural light. I have a collapsible for photography and videography.

Laptop Gadgets

I don’t usually buy very expensive gadgets unless it’s really good. I am all about frugal engineering. I usually try to find fairly low budget items that can do exactly what expensive branded ones can do. So here is what I use:

Keyboard:
I use a bluetooth wirless keyboard by Arteck. It’s a stainless steel sleek design that is compatible for IOS, Android and Windows. Sometimes I even connect to my phone to reply to messages faster.

I also recommend another one, which is also cheaper and has 7 different backlight option as well (Looks really cool at night). I initially had this one, but returned it because it was little small for me (Only 247mm in width). However, this is actually a great portable keyboard and is compatible with IOS,Android and Windows.

Wireless Mouse:
I use a fairly good looking wireless bluetooth mouse with two additional buttons on the side for moving back and forward on website. I am not a big fan of the scrolling button, but for £11.99 on amazon, I cannot really complain.

Animating a plot in Matlab is very easy. Watch my tutorial below:

Tutorial 1 | How to change to a dark theme

Unfortunately Matlab doesn’t have an option to completely switch everything to a dark them with one click. However, we can do some manual tweaking to create a custom dark environment. So below are two screenshots showing you the colours you need to set up the same colour scheme I have shown you in my tutorial. The only custom colours that I am using (which i copied form Android Studio) are the following:

Background : 2B2B2B
Error Text : FC6462
Unterminated strings : FC6462

Every other colour apart from the above mentioned are available in your Matlab palette. You can also get the RGB code for all the colours using the tool I showed you in the tutorial from colorZilla.com. Enjoy!

Tutorial 2 | How to Plot a Circle in Matlab

The parametric equation of a circle can be defined as follows:

xCoordinate = xCenter + Radius x Cos(theta)
yCoordinate = yCenter + Radius x Sin(theta)

Tutorial 7 | Difference between Vectors, Matrices & Arrays

1. Difference between Vectors,Matrices & Arrays

Figure 1: Difference sub-categories of an array

2. Array Operations (Addition,Multiplication)
If you add a number to an array, that number will be added to each element in the array. Same applied for multiplication, subtraction and division. For example:
m = [1 1 1];
m + 2 = [3 3 3];
