说明：  可以方便地进行1,2范数的优化计算。具体针对稀疏恢复问题，最小二乘问题，约束优化问题的求解等。(It is convenient to optimize the calculation of 1,2 norms. Specifically for sparse recovery problem, least squares problem, constrained optimization problem and so on.)

MATLAB教程各章配套程序 对大家一定有帮助，很全面的啊(MATLAB tutorial chapters of the matching program will certainly be helpful to everyone, very comprehensive, ah)

matlab本身没有绘制三轴曲线的命令，附件放入matlab命令文件夹中可用plotyyy命令调用(matlab triaxial curve itself does not draw commands into matlab command attachment folder available plotyyy command calls)

说明：  AUC calculation, including mapping, calculation value
