matlab与C的混编，处理乘性噪声，建立M次开根号模型，需要调整参数。-written with matlab and C by S. Yun and H. Woo, "A new multiplicative denoising variational model based on m-th root transformation".

利用matlab中的GUI实现一个简易计算器的功能，包含加、减、乘、除、开根号、取对数等基础运算功能，还可进行按位清零和全部清零。(a simple calculator and you can use it to realize add, subtract, multiply and divide.)
