Function Documentation

oski_value_t rand_GenValue (  double  a,
double  b
) 
 

Returns a random value in the interval $[a, b]$.

If oski_value_t is complex, then the real and imaginary parts each lie in the interval.

oski_value_t rand_GenValueReal (  double  a,
double  b
) 
 

Returns a random pure real scalar in the interval $[a, b]$.

Thus, if oski_value_t is complex, then the imaginary part is set to 0.
