hpStat

Compute descriptive statistics of a pixel value list

Contents

Syntax

stats = hpStat(v)

Input Arguments

v         array of HEALPix pixel values

Output Arguments

stats     struct
          field     contents
          ntot      total number of data points
          nvalid    number n of valid data points
          mind      minimum of valid data
          maxd      maximum of valid data
          average   average of valid points
          absdev    absolute deviation
          var       variance
          stddev    standard deviation
          skew      skewness factor
          kurt      kurtosis factor

Example

display stats of Y_3^1

v = ylm(32,3,1,'real',true);
stats = hpStat(abs(v))

stats = 

      ntot: 12288
    nValid: 12288
      mind: 1.0813e-18
      maxd: 0.6289
      mean: 0.2272
    absdev: 0.1421
       var: 0.0280
    stddev: 0.1673
      skew: 0.5111
      kurt: 2.2410
