Matrix.lua Link

: Allows you to pass any anonymous function, such as function(val) return math.max(0, val) end (ReLU activation).

-- Example: Apply a sigmoid function to all elements local sigmoid = function(x) return 1 / (1 + math.exp(-x)) end local activated_matrix = matrix.map(my_matrix, sigmoid) Use code with caution. Why this is a "Good" Feature matrix.lua

: By integrating this into the core library, you can ensure it handles table indexing in a way that minimizes overhead, which is a common bottleneck for large matrices (e.g., 250x250 or larger). : Allows you to pass any anonymous function,
