I wish to generate psuedo-random numbers/permutations that \'occupy\' a full period or full cycle within a range. Usually an \'Linear Congruential Generator\' (LCG) can be used to generate such sequen
I need an algorithm to perform a 2D bisection method for solving a 2x2 non-linear problem. Example: two equations f(x,y)=0 and g(x,y)=0 which I want to solve simultaneously. I am very familiar with th
I have written a program which writes a list of data to a \'.dat\' f开发者_运维技巧ile with the intention of then plotting it separately using gnuplot.Is there a way of making my code plot it automati
Without resorting to asymptotic notation, is tedious step counting the only way to get the time complexity 开发者_开发问答of an algorithm? And without step count of each line of code can we arrive at
So I just fixed an interesting bug in the following code, but I\'m not sure the approach I took it the best:
I need to count the quantiles for a large set of data. Let\'s assume we can get the data only through some portions (i.e. one row of a large matrix). To count the Q3 quantile one need to get all the
Is there a constant that stores the machine epsilo开发者_开发技巧n in R?Try .Machine$double.eps -- and .Machine which on my 32-bit Linux machine yields this:
i\'m trying to do factor analysis for a co-occurrence ma开发者_JAVA技巧trix(C) , which is computed from the term-document matrix(TD) as follows:
Given a binary number that repeats, for example 0.(0011) or 0.0(101), how would one go about converting it to decimal?
R question: Looking for the fastest way to NUMERICALLY solve a bunch of arbitrary cubics known to have real coeffs and three real roots. The polyroot fu开发者_StackOverflow社区nction in R is reported
