EngagementStruct

MATLAB

S = EngagementStruct(G)

Description

Returns a structure of engagement parameters for custom scenarios, given platform position and velocity vectors and target position and velocity vectors in a defined coordinate system.

Parameters

Parameters	Description
G [struct/string]	Identifier for platform/target engagement scenario. Can be a structure from GeomStruct or a case code string (refer to SCALE and/or SHARE toolboxes, if available)
