Syntax and Description

stat(variable) prints the following properties of a variable in the command window:

  • size: size of variable.
  • numel: number of elements in variable.
  • NaNs: number of not-a-number values in variable.
  • maximum: maximum value in variable across all dimensions.
  • minimum: minimum value in variable across all dimensions.
  • mean: mean value of variable across all dimensions.
  • median: median value of variable across all dimensions.
  • mode: most frequent value in variable across all dimensions.
  • std dev: standard deviation of variable across all dimensions.
  • variance: variance of variable across all dimensions.

Examples

A = magic(5)
A =
    17    24     1     8    15
    23     5     7    14    16
     4     6    13    20    22
    10    12    19    21     3
    11    18    25     2     9
stat(A)
 
 Properties of A:
 size     = 5  5
 numel    = 25
 NaNs     = 0
 maximum  = 25
 minimum  = 1
 mean     = 13
 median   = 13
 mode     = 1
 std dev  = 7.3598
 variance = 54.1667
 

This function also works with NaN values:

A(2:4)=NaN
A =
    17    24     1     8    15
   NaN     5     7    14    16
   NaN     6    13    20    22
   NaN    12    19    21     3
    11    18    25     2     9
stat(A)
 
 Properties of A:
 size     = 5  5
 numel    = 25
 NaNs     = 3
 maximum  = 25
 minimum  = 1
 mean     = 13.0909
 median   = 13.5
 mode     = 1
 std dev  = 7.2697
 variance = 52.8485
