Random number generator between two numbers - MatLab

Question

I am trying to create a random number generator between two numbers in MatLab but I am unable to figure out the correct equation.

I know that you can use the rand() function to create random numbers but what if I wanted to have numbers only generated between -.5 and .5? Is this possible to accomplish in MatLab?

Answer 1

The answer for adjusting the interval is listed in the help section on rand() :

Example 1

Generate values from the uniform distribution on the interval [a, b]: r = a + (b-a).*rand(100,1);
