rms

PURPOSE ^

RMS calculates the root mean square

SYNOPSIS ^

function o=rms(x,DIM,W)

DESCRIPTION ^

 RMS calculates the root mean square
   can deal with complex data. 

 y = rms(x,DIM,W)

 DIM    dimension
    1 STD of columns
    2 STD of rows
     N STD of  N-th dimension 
    default or []: first DIMENSION, with more than 1 element
 W    weights to compute weighted s.d. (default: [])
    if W=[], all weights are 1. 
    number of elements in W must match size(x,DIM) 

 y    estimated standard deviation

 features:
 - can deal with NaN's (missing values)
 - weighting of data 
 - dimension argument also in Octave
 - compatible to Matlab and Octave
