Data statistics

Syntax

xds = datastats (x) [xds,yds] = datastats(x,y)

Description

xds = datastats (x)returns statistics for the column vectorxto the structurexds. Fields inxdsare listed in the table below.

Field	Description
`num`	The number of data values
`max`	The maximum data value
`min`	The minimum data value
`mean`	The mean value of the data
`median`	The median value of the data
`range`	The range of the data
`std`	The standard deviation of the data

[xds,yds] = datastats(x,y)returns statistics for the column vectorsxandyto the structuresxdsandyds, respectively.xdsandydscontain the fields listed in the table above.xandymust be of the same size.

Examples

Compute statistics for the census data incensus.mat:

load census [xds,yds] = datastats(cdate,pop) xds = num: 21 max: 1990 min: 1790 mean: 1890 median: 1890 range: 200 std: 62.048 yds = num: 21 max: 248.7 min: 3.9 mean: 85.729 median: 62.9 range: 244.8 std: 78.601

Tips

Ifxorycontains complex values, only the real parts are used in computing the statistics. Data containingInforNaNare processed using the usual MATLAB^®rules.
