Description
Returns a real matrix containing random elements that are uniformly
distributed between 0 and 1,
where rows is the number of rows and
cols is the number of columns.
The arguments rows and cols are integer,
real, double-precision or complex scalars.
If an argument is complex, only its
real part
is used.
If the argument cols is not present,
a square matrix
is returned.
Example
clear
rand(3, 1)
results in
{
4.65661e-010
0.527357
0.384887
}
The rand function returns values from a pseudo-random sequence.
It always starts at the same point at the beginning of an O-Matrix session
and after a clear.
If you continue the previous example by entering
clear
rand(3, 1)
O-Matrix will respond
{
4.65661e-010
0.527357
0.384887
}
which are the same as the numbers output above.
If, however, you continue the previous example (without clearing)
by entering
rand(3, 1)
O-Matrix will respond
{
0.134948
0.223919
0.643237
}
which is a different set of numbers.
Reference
The arguments must be scalars. If they are logical, real, double-precision
or complex, the corresponding integer
values are used.
