描述----------Description----------
Compute the Average Standard Deviation for a Set of Spectra and a Given Cutoff Point
为一个集光谱计算的平均标准偏差和一个给定的分界点
用法----------Usage----------
avesd(Ma, cutoff)
参数----------Arguments----------
参数:Ma
A matrix with rows the m/z values and columns samples/spectra
一个行矩阵的m / z值和列样品/光谱
参数:cutoff
A number of m/z
许多的m / z
Details
详情----------Details----------
For a given cutoff point, the standard deviation of all spectra will be calculated at each m/z above this cutoff point. The resulting sd's are then averaged and returned.
对于一个给定的分界点,将所有光谱的标准偏差计算,每超过这个分界点的m / z。造成SD的平均和返回。
