From: Composite mathematical modeling of calcium signaling behind neuronal cell death in Alzheimer’s disease

Equation Biological significance
stepupf=heav(tinit) Heaviside step up function
stepdownf=heav(t−(init+duration)) Heaviside step down function
IP3=baseline+amplitude(stepupfstepdownf) IP3 step function
