Function File: [m, v] = wblstat (scale, shape)

Compute mean and variance of the Weibull distribution.

Arguments

  • scale is the scale parameter of the Weibull distribution. scale must be positive
  • shape is the shape parameter of the Weibull distribution. shape must be positive

scale and shape must be of common size or one of them must be scalar

Return values

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

Examples

scale = 3:8;
shape = 1:6;
[m, v] = wblstat (scale, shape)



[m, v] = wblstat (6, shape)
