Wavelet Approximation Methods And Applications

Mathematical approximation theory is the mathematical one of the fastest growing areas. In recent decades, science and technology and the widespread use of computers to its development with a strong motion. Modern mathematics, including basic mathematics, computational mathematics, applied mathematics and approximation of a number of branches is inextricably linked. Function approximation theory is a branch of mathematics developed into mutual contact with many practical and comprehensive nature of the subject with certain.As a function approximation of an important component of the spline approximation method and the sampling theorem has gradually developed into an important research topic. Although it is derived from the common practice of the more basic functions, but the spline theory itself and its application in numerical analysis have made a very important development, particularly in approximation theory, spline theory of the status of growing the same time, The new interesting results are emerging. For the approximation of entire functions of exponential type of signal analysis is one of the important areas, we use the second derivative of the deformation with a spline-based reconstruction of thentire function that obtained the same results of convergence.
