介绍压缩传感理论中要用到的信号的稀疏表征原理(Introduced the theory of compressed sensing to use the sparse representation of signal theory)

Design a fuzzy system to approximate a function the function may not be defined analytically but the values of the function in n point is defined for example : x E [-3 3] g(x)=sin(x) the approximation is calculated a fuzzy set design our fuzzy function approximates sin function with an error less than 0.2 note : this program uses a function named isinrange so copy it to your directory
