This course introduces students to high-performance array computing in C++ using the Eigen library, a versatile template library for linear algebra, matrices, and vectors. Participants will learn to leverage Eigen's expressive syntax and optimized computations for efficient numerical operations. The course covers fundamental concepts such as matrix operations, vector manipulations, and array broad
