Numerically

The samples of code included numerically solve the diffusion equation as it arises in medical imaging. This process is done with multiple solution methods, various boundary conditions, and in multiple dimensions.

The STP IdealGasNumberOfStates program numerically evaluates the number of states of an ideal gas and demonstrates finite size effects by plotting the actual number of states and the asymptotic expression. The default is two-dimensional system (d=2). STP IdealGasNumberOfStates is part of a suite...
