Since the question is tagged R, I assume that you are looking for a solution in R? If so, simply type:

runif(n=10,min=-5,max=5)

runif is short for 'random uniform', so the above asks for 10 random uniformly distributed numbers in the interval [-5;5]

For more info on function type

?runif

Btw. if you are interested in being able to reproduce your results, you should look into the set.seed() function.

use the following:

range = 5;

Y = (2*range*rand(m, n))-r;

Now the value of Y will be floating point numbers with in the range of -5 to 5.

In matlab, simply

    rand*10-5

can generate a random float ranging [-5,5].

Apart from above suggested methods, there are also various mathematical subroutines to generate random numbers i.e. Mid-Square method( what L.E. Jessen suggested), Congruence methods with largest prime modulo.(Ref. Book, Simulation: Seldon Ross).

Otherwise,

1. Generate between (0,1); say 'r' of length at least four.

2. random no. = (+/-)5*r

3. Discard integers if not required.

Generating random numbers in (0,1) by rand(), numbers will be uniform and independent. Further, there will be no auto correlation. The sequence of random numbers will be almost cycle free.

rand(m,n).*10-5

range=(5+(-5))=10

lower=-5

rand(m,n).*range+lower

Cod in c language is

void main()

{

unsigned int iseed = (unsigned int)time(NULL);

double random_number=-5 +    (rand()%100)/10;

}

// description of the code 

rand() represent random number between 0 to 32000 . If want to convert between -5 and +5 then first % by 100 which gives you number 0 to 99 then divide number by 10 which gives you number between 1 to 10. Next step is to add with -5 . finally gives you number between -5 to +g

/////////////////////////////////code in java language...//////////////////////////////////////////////////

public static void main()

{

int k=(Math.random()-5 +10); gives u number between -5 and +5

}

////////////////Both codes are executable try it///////////////////////////////////////////////////////

if you need more help in coading just post the messgae
