cdfWeibull ============================================== Purpose ---------------- Computes the cumulative distribution function for the Weibull distribution. Format ---------------- .. function:: p = cdfWeibull(x,shape,scale) :param x: Values at which to evaluate the cumulative distribution function for the Weibull distribution. :math:x \geq 0. :type x: NxK matrix, Nx1 vector or scalar :param shape: Shape parameter. ExE conformable with *x*. :math:shape > 0. :type shape: NxK matrix, Nx1 vector or scalar :param scale: Scale parameter, ExE conformable with *x*. :math:scale > 0. :type scale: NxK matrix, Nx1 vector or scalar :return p: Each element in *p* is the cumulative distribution function of the Weibull distribution evaluated at the corresponding element in *x*. :rtype p: NxK matrix, Nx1 vector or scalar Examples ---------------- Calculate the cdf for the Weibull distribution with different shape parameters. :: // Values x = seqa(0,0.01,301); // Shape parameter shape = 0.5~1~1.5~5; // Scale parameter scale = 1; p = cdfWeibull(x, shape, scale); plotxy(x, p); After running above code, .. figure:: _static/images/cdfWeibull_1.png Remarks ------------ The Weibull cumulative distribution function is defined as: .. math:: f(x; k, \lambda) = 1 - e^{-(x/\lambda)k} .. seealso:: Functions :func:pdfWeibull, :func:cdfWeibullInv
