How can I free memory after creating Matplotlib?
These stackoverflow posts suggested that I can free the memory used by matplotlib objects with the following commands: .close(): Python matplotlib: memory is not freed when specifying the size of the figure

Why is Matplotlib slower than realtime visualization?
Just a quick note, depending on your exact use case, matplotlib may not be a great option. It is geared towards publication quality figures, not real-time viewing. However, there are many things you can do to speed up this example. There are two main reasons why this is so slow.
Why do Python programs use so much memory?
Python uses built-in memory management and garbage collection to ensure that your program only uses the amount of RAM that it needs. So unless you expressly write your program in such a way as to increase memory usage, for example by creating a database in RAM, Python only uses what it needs. Which begs the question, why would you want to use more RAM?
What is the best way to use Matplotlib?
This tutorial covers some basic usage patterns and best practices to help you get started with Matplotlib.
How to create a for loop in R?
In the following R code, we are specifying within the for loop header that we want to execute an array containing ten elements from the first element (ie 1) to the last element (ie 10). Inside the body of the for loop, we create an output called x1, which contains the index of our loop raised to the power of 2.
Why does advanced ask for large chunks of memory?
After all, allocating large amounts of memory is something operating systems are very good at. Beyond 128 bytes, R will request memory in multiples of 8 bytes. This ensures good alignment. One subtlety of object size is that components can be shared between multiple objects. For example, look at the following code:
How are objects stored in memory in advanced R?
Object metadata (4 bytes). This metadata stores the base type (for example, an integer) and information used for debugging and memory management. Two pointers: one to the next object in memory and one to the previous object (2 * 8 bytes). This doubly linked list makes it easy for the internal R code to loop through all the objects in memory.
