Modified ELM MATLAB Algorithm with Enhanced Performance

My improved MATLAB implementation of Extreme Learning Machine (ELM) neural network algorithm demonstrates significantly faster computational speed when using more than 3 neurons. The key enhancement utilizes function-based column matrix generation techniques. ELM is fundamentally a rapid neural network algorithm, and through comparative testing, I've verified it outperforms many popular algorithms (BP, SVM) in both speed and effectiveness. This implementation runs in MATLAB environment and supports testing with all benchmark datasets.
