Function partition_function_kernel 

pub fn partition_function_kernel(
    energies: &CausalTensor<f64>,
    temp: Temperature,
) -> Result<f64, PhysicsError>

Calculates Partition Function: $Z = \sum e^{-E_i / k_B T}$.

Arguments

• energies - List of energy states (Tensor).
• temp - Temperature $T$.

Returns

• Result<f64, PhysicsError> - Partition function $Z$.
