Data types of variables in Matlab

Let's talk about data types of variables in Matlab.

So, when you create a variable in Matlab, it automatically takes on a data type based on the value that you assign to it. For example, if you assign a character to a variable, it becomes a char data type. Simple enough, right?

Now, let's take a closer look at some of the different data types that you can use in Matlab.

• Char
  First up, we have char data types. These are used to store characters and strings, with each character taking up 8 bits (1 byte) of memory.
• Logical
  Next, we have logical data types, also known as boolean variables. These can only take on two values: 1 (True) or 0 (False). They're often used in conjunction with logical operators like AND, OR, and XOR.
• Int
  Moving on to integer data types. These are used to store whole numbers, with the size of the variable depending on the number of bits. So, for example, you can have int8 (8-bit), int16 (16-bit), int32 (32-bit), or int64 (64-bit) data types.
  

  Note. For unsigned integer numbers (int), there is a specific data type: uint8 (8 bits), uint16 (16 bits), uint32 (32 bits), uint64 (64 bits).

• Double o single
  Finally, we have double and single data types. These are used to store decimal real numbers with floating-point precision. Single precision variables take up 4 bytes (32 bits), while double precision variables take up 8 bytes (64 bits)..
• Double o single complex
  If you're working with complex numbers, you can also use single complex and double complex data types. These allow you to store both the real and imaginary parts of a complex number separately.

So there you have it. A brief rundown of the different data types you can use in Matlab. Hopefully, that wasn't too complicated!
