VSTD Standard deviation over non-NaN elements along a specfied dimension. Y=VSTD(X,DIM) takes the standard deviation of all non-NaN elements of X along dimension DIM. [Y,NUM]=VSTD(X,DIM) also outputs the number of non-NaN data points NUM, which is the same size as X. VSTD uses the "1/N" normalization, where N is the number of data points, rather than the "1/(N-1)" normalization. [Y1,Y2,...YN]=VSTD(X1,X2,...XN,DIM) also works. VSTD(X1,X2,...XN,DIM); with no arguments overwrites the original input variables. __________________________________________________________________ This is part of JLAB --- type 'help jlab' for more information (C) 2001--2015 J.M.
