Matrix.lua -

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

: It moves beyond standard arithmetic (add/sub/mul) to support any mathematical transformation. matrix.lua

: Extend it to accept multiple matrices of the same size, allowing for element-wise operations between them (like c[i][j] = f(a[i][j], b[i][j]) ). Implementation Concept : Allows you to pass any anonymous function,

-- 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 such as function(val) return math.max(0
