Items tagged with uniform


I have found very little help about the Generate command of the RandomTools package.

I also have minor gripes about the syntax. And what better way to deal with these than to voice them?

This is how I was able to generate random lists and random Matrices.

A list of 10 random integers between 1 and 100:

L := RandomTools:-Generate(list(integer(range=1..100),10));

      L := [47, 8, 46, 44, 9, 77, 59, 16, 1, 70]


To plot the density function of the continuous uniform distribution on [-1,1], my initial attempt was: 

plot(Statistics:-PDF(Statistics:-RandomVariable(Uniform(-1,1)),x), x = -1.1 .. 1.1);

See plot below.

But I wanted something more like the wikipedia image (without the labels, naturally):

See plot below.

In words, I expected a horizontal line on the left of x=-1 and on the right of x=1 (at y=0), and I expected no vertical line at the x=-1 and x=1 points ...

This is more of a blog entry, mostly a note to myself.

I wanted to generate a list of points on the surface of a deformed sphere. It turns out that Robert recently showed how to do that on a unit sphere.

Adapting his code is straightforward. So here is what I came up with. One proc generates the random points on the surface of the ellipsoid. Another proc generates...
