The Gram-Schmidt Process is a fundamental algorithm in linear algebra used to orthogonalize a set of linearly independent vectors. It transforms these vectors into an orthogonal or orthonormal basis, preserving the dimensions of the space while establishing orthogonality. This method is crucial in various fields, including computer graphics, signal processing, machine learning, and numerical analysis, due to its ability to simplify vector operations and improve computational efficiency.
