Illustrations of calling the rand function:

The function ‘rand’ can be used to produce random real numbers; calling it produces one random real number in the range from 0 to 1. There is no argument passed to the rand function. Here are two illustrations of calling the rand function:

>> rand

ans =

0.9501

>> rand

ans =

0.2311

The seed for the rand function will always be similar each time the MATLAB is started, unless the state is changed, for illustration shown:

 

rand(‘state’,sum(100*clock))

 

This uses the present date and time which are returned from the built-in clock function to set the seed. Note: this is completed only once in any given MATLAB session to set the seed; the rand function can be used as shown earlier in any number of times to produce random numbers.

As rand returns a real number in the range from 0 to 1, multiplying the answer by an integer N would return the random real number in a range from 0 to N. For illustration, multiplying by 10 returns a real in the range from 0 to 10, therefore this expression

rand*10

would return the outcome in the range from 0 to 10.
