gfortran - random number generator in fortran - i testing rng code mentioned in link (fortran 77 code): https://www.cisl.ucar.edu/zine/96/spring/articles/3.random-6.html applies park & miller algorithm. the function phone call of programme is call srand(seed) x=rand() however programme not seem respond seeding srand(), i.e., x-value unaffected initial seeding, , equal ~0.218. suspect has definition of mutual block , info block, value of x equivalent putting seed 123456789, initialization value defined in datablock. any ideas? i compiling gfortran. ok, problem original srand , rand may called. renamed functions srand2 , rand2 , start work expected. for seed = 1 result 7.82636926e-06 , seed = 2 result 1.56527385e-05 . checked in gfortran , in intel's fortran. fortran gfortran prng fortran-common-block

matlab - How to generate random matrix without repetition in rows and cols? - how generate random matrix without repetition in rows , cols specific range example (3x3): range 1 3 2 1 3 3 2 1 1 3 2 example (4x4): range 1 4 4 1 3 2 1 3 2 4 3 2 4 1 2 4 1 3 this algorithm trick, assuming want contain elements between 1 , n %// elements contained, no 0 allowed = [1 2 3 4]; %// possible permutations , size n = numel(a); %// initialization output = zeros(1,n); ii = 1; while ii <= n; %// random permuation of input vector b = a(randperm(n)); %// concatenate found values temp = [output; b]; %// check if row chosen in iteration exists if ~any( arrayfun(@(x) numel(unique(temp(:,x))) < ii+1, 1:n) ) %// if not, append output = temp; %// increment counter ii = ii+1; end end output = output(2:end,:) %// delete first row zeros it won't fastest implementation. curios see others. computation time in...
