The Redis-ML module provides matrix operations for processing Matrix data using the Redis database, adding matrices as a native Redis data type and supporting mathematical operations like multiplication and addition. It allows users to read and write matrix values through specific commands, such as ML.MATRIX.SET and ML.MATRIX.GET, which use row-major format. The module can perform basic matrix equations like y = Ax + b by combining multiple matrices using commands like ML.MATRIX.MULTIPLY and ML.MATRIX.ADD. Additionally, it enables users to scale a matrix using the ML.MATRIX.SCALE command, resulting in a new matrix with the same dimensions but scaled values. Matrices are used for various applications including linear transforms and multivariate probability distributions, making Redis-ML a valuable tool for data processing and analysis.
