Function Reference: gamstat

statistics: [m, v] = gamstat (a, b)

Compute statistics of the Gamma distribution.

Arguments

  • a is the first parameter of the gamma distribution. a must be positive
  • b is the second parameter of the gamma distribution. b must be positive

a and b must be of common size or one of them must be scalar

Return values

  • m is the mean of the gamma distribution
  • v is the variance of the gamma distribution

Examples

 
 
 a = 1:6;
 b = 1:0.2:2;
 [m, v] = gamstat (a, b)
 
 
 [m, v] = gamstat (a, 1.5)
