一个可以在matlab中实现对图形进行局部放大的程序，可以直接放在matlab的工具箱里进行调用使用-Graphics can be achieved on a partially enlarged program in matlab, it can be placed directly matlab toolbox called with

图形的放大截取处理，matlab中画的任何图形都可以用这个程序来放大，放大之后的图形会自动生成相应的坐标系。(The magnification of the graph is taken, and any figure drawn in matlab can be amplified by this program, and the corresponding coordinate system will be automatically generated after the zoom.)
