Weibull cumulative distribution function (cdf).
Syntax
P = weibcdf(X,A,B)
Description
weibcdf(X,A,B) computes the Weibull cdf with parameters A and B at the values in X. The arguments X, A, and B must all be the same size except that scalar arguments function as constant matrices of the common size of the other arguments. Parameters A and B are positive. The Weibull cdf is:
Examples
What is the probability that a value from a Weibull distribution with parameters a = 0.15 and b = 0.24 is less than 500?probability = weibcdf(500,0.15,0.24)
probability =
0.4865
How sensitive is this result to small changes in the parameters?
[A,B] = meshgrid(0.1:0.05:0.2,0.2:0.05:0.3);
probability = weibcdf(500,A,B)
probability =
0.2929 0.4054 0.5000
0.3768 0.5080 0.6116
0.4754 0.6201 0.7248
