Description: Returns the Weibull distribution.
Syntax: weibulldist(x, Beta, Eta, Gamma, Cumulative)
x is the time at which the function is evaluated.
Beta is the shape parameter of the Weibull distribution.
Eta is the scale parameter of the Weibull distribution.
Gamma is the location parameter of the Weibull distribution.
Cumulative is a logical value that indicates which form of the Weibull function to provide. If the value is TRUE, it returns the cumulative distribution function; if FALSE, it returns the probability density function.
Remarks:
x, Beta, Eta and Gamma must be numerical.
x, Beta and Eta must be > 0.
Cumulative can be either 1 or TRUE for TRUE, or any other value or FALSE for FALSE.
All parameter values can include:
Numerical values
Standard operands (+, -, *, /)
Predefined mathematical functions (exp, log, sin, etc.)
