Numerical calculation is the basis for numerically analyzing and simulating the real world using computers. In this class, we learn the essential knowledge of numerical calculation and some famous methods and algorithms in order to apply them to the real world analysis.

### Student learning outcomes

・Learn how to model the real world and how to numerically analyze the model using computers
・Learn the important topics when you perform numerical analysis (e.g., errors, loss of digits)
・Learn numerical solution of simultaneous linear equations
・Learn numerical solution of nonlinear equations
・Learn numerical differentiation and numerical integral, and apply them to numerical solution of ordinary/partial differential equations
・Learn interpolation and data fitting based on least-square method

### Keywords
