Calling Sequence

Parameters

Description

Examples

Calling Sequence

DEdetermine(ode, var)

Parameters

ode

-

ordinary differential equation

var

-

dependent variable, e.g., yx

Description

• 

The DEdetermine command performs some sanity checks on the given ordinary differential equation and returns an LODEstruct data structure.

• 

The first argument should be a differential equation in diff notation or in D operator notation. If ode is an expression, then it is equated to zero.
