MATLAB_FFT

说明：  乘积的最后三位的值只与乘数和被乘数的后三位有关，与乘数和被乘数的高位无关，利用此来求尾数(The last three values of the product only with the multiplier and the multiplicand on the back three, with a high multiplier and the multiplicand has nothing to do, take advantage of this to seek mantissa)

说明：  详细介绍matlab中用来处理图像的工具箱以及工具箱的具体运用方法(Details matlab image processing toolbox used to the concrete application of methods and tool kit)

matlab开发的，基于行作用技术的代数迭代算法反演代码。可用于层析成像(matlab developed algebraic algorithms based on the role of technology line inversion code. Can be used for tomographic imaging)
