MATLAB: How to generate a random number that is negative or positive and between two other values

functionsrandom number generator

I need to write a function that generates two numbers that are between the negative and positive values of an integer. For example, if I call the function and input 7 it should generate two random numbers between -7 and +7. I can't figure out a way to use the randi function because the values I need can't be just integers.

a = -5 ;
b = -1.670000000000000 ; 
r = (b-a).*rand(1000,1) + a;

MATLAB: Geomean on returns with negative values

Use

GR=100*(prod(1+R/100)^(1/numel(R))-1);

where R is the rate of return for the period.

Example:

>> R=[9 1 2 3 -1];                            % sample rate of returns, %
>> GR=100*(prod(1+R/100)^(1/numel(R))-1)      % geometric rate of return
GR =
    2.7458
