dosage_ode


dosage_ode, a MATLAB code which sets up and solves a system of ordinary differential equations (ODE) to simulate the blood levels of a medicinal drug that should stay between medicinal and toxic limits.

The drug level can be modeled by a set of first-order linear differential equations. If we define:

  A = medicine_in_intestines,
  B = plasma_level.  
then the governing differential equations are:
  dA/dt = - absorption_rate * A + intake
  dB/dt = - excretion_rate  * B + absorption_rate * A
