WHILE:
The RLaB while statement is similar to the C while statement.
Example:
> i=1;
> while(i<10)
{
a[i] = 1.3*i;
i++;
}
> a
a =
matrix columns 1 thru 5
1.3 2.6 3.9 5.2 6.5
matrix columns 6 thru 9
7.8 9.1 10.4 11.7
while(0) { "this will never be executed" }
If the conditional evaluates to zero then the loop is not
executed, if it evaluates to anything other than zero it will
be executed until the condition is zero.
