Function mixDensityMatrix

Source 
pub unsafe extern "C" fn mixDensityMatrix(
    combineQureg: Qureg,
    prob: f64,
    otherQureg: Qureg,
)
Expand description

Modifies combineQureg to become (1-\p prob)\p combineProb + \p prob \p otherQureg. Both registers must be equal-dimension density matrices, and prob must be in [0, 1].
