ghost
- 求解 吸血鬼数字。吸血鬼数字是指 位数为偶数的数字,可以由一对数字相乘而得,而这对数字包含乘积的一半位数的数字,其中从最初的数字中跌取的数字可以任意排序,以两个0结尾的数字是不允许的。 如 91=9*9; 1344=32*42-Solving vampire figures. Vampire figures refer to the median figure is an even number can be multiplied by a figure derived from, whic
simpson

NEWTPO
- 用Newton法或Newton-Maehly方法求实系数多项式方程的实根。-Realistic coefficient Newton method or the Newton-Maehly method, the real roots of polynomial equations.
cmean
- 对于有缺测值的数据取平均 使用: y=cmean(x,k,c) x为包括有nan的数据,仪器观测中经常会出现 k为对x取第几维方向的平均 c的值可以控制缺测的条件,例如c取50,表示这一维方向上,如果有值的观测超过50个值才取平均,否则取nan;如果c取-5,表示缺测数在5以下时才做平均,否则返回nan-calculate the statistical mean of data but tick off nan Usage y=cmean(x,|k) or y
