Using random generator with probability using matlab

THe following code generates random numbers with a given probability of success: n=[randi([0 1],1,8) ones(1,8)]; n= n(randperm(10)); If the above lines are repeated random (unpridictable) values will be generated: This is n for the first run: n = 1 0 1 0 0 1 1 1 1 1 This is n for the second run: n = 1 1 1 0 1 1 1 1 1 1 How can I make...

Generate random numbers distributed by Zipf

Zipf probability distribution is often used to model file size distribution or item access distributions on items in P2P systems. e.g. "Web Caching and Zip like Distribution Evidence and Implications" , but neither Boost or the GSL (Gnu Scientific Library) provide an implementation to generate random numbers using this distribution.

Sixth form rutherfords alpha scattering probablility

Ok basically my textbook says that because there is a probability of 1 in 10000 that a alpha particle will be deflected by more than 90 degrees and that for n layers the probability of deflection is 1 in 10000n. This means that as more layers are added the probability of deflection by a given atom decreases. Could anyone explain this as I...

Responsive MATLAB GUI without calling drawnow() directly

Facts about MATLAB: MATLAB UI is Java Swing.

How do I plot multiple probability distributions side-by-side in R?

I want to plot several probability distributions side-ways (density on the x-axis, variable on y-axis). Each distribution will be associated with a different category, and I want them side-by-side so that I can compare between them. This is a bit like a box-plot but instead I want an theoretical probability distribution that I will specif...

C executable from Matlab and/or R

The Matlab toolbox 'Matlab coder' allows you to generate ANSI C source code (as long as it does not involve any sophisticated toolboxes – at least for now). Given this discussion: SO disussion I understand that R can also produce (at least?) 'object' files from R (version greater 2.13). I presume these could also be linked later to build...

Undergraduate Probability of a homozygous recessive offspring from first cousins

1 in 25 people are cystic fibrosis carriers. What is the probability of of a recessive homozygote child from two first cousins? The answer is (1/25)*(1/4)*(1/8) =1/800 I don't understand how to work this out. The 1/8 is the conditional probability that both cousins are carriers. But I get 1/16, though I think I'm getting this "conditional...
