The equation is written as a system of two first-order ordinary differential equations (ODEs). These equations are evaluated for different values of the parameterμ. For faster integration, you should choose an appropriate solver based on the value ofμ. Forμ=1, any of the MATLAB ODE solvers...

Delay differential equations (DDEs) are commonly used in pharmacometric models to describe delays present in pharmacokinetic and pharmacodynamic data analysis. Several DDE solvers have been implemented in NONMEM 7.5 for the first time. Two of them are based on algorithms already applied elsewhere, whil...
The classical approach in PKPD is to apply transit compartment models (TCM) based on ordinary differential equations to handle such delays. However, an alternative approach to deal with delays are delay differential equations (DDE). DDEs feature additional flexibility and properties, realize more ...
