numpy is a powerful set of blocks that allows you to work with arrays and matrices of numbers directly in Scratch. With it, you can perform a wide range of operations: from simple arithmetic operations to complex mathematical calculations and the use of activation functions (ReLU, Sigmoid, Tanh). The main advantage of this tool is that now working with matrices has become much easier and more accessible, without having to create your own abstractions or write complex code. See the details of each block in the README sprite.
