I am fitting a Weibull distribution to a set of data "x" (10000 x 1). I want the distribution to have the same size. I am trying the following code

XLim = get(gca,'XLim');
XLim = XLim + [-1 1] * 0.01 * diff(XLim);
XGrid = linspace(XLim(1),XLim(2),10000);
f_Weibull = fitdist(x, 'weibull'); 
f = pdf(f_Weibull,XGrid)';

However, somehow my PDF ends up being only NaN numbers, how can I solve this?

P.S.: using R2013a

This code ran just fine for me, in 2015b:

rng 'default'
x = wblrnd(1.5,1.3,10000,1);
XLim = get(gca,'XLim');
XLim = XLim + [-1 1] * 0.01 * diff(XLim);
XGrid = linspace(XLim(1),XLim(2),10000);
f_Weibull = fitdist(x, 'weibull'); 
f = pdf(f_Weibull,XGrid)'
