BlockDiagnostic

Diagnostic information for individual block linearization

Description

When you linearize a Simulink model, you can create a LinearizationAdvisor object

that contains BlockDiagnostic objects. Each BlockDiagnostic object contains

diagnostic information regarding the linearization of the corresponding Simulink block.

You can troubleshoot the block linearization by examining the BlockDiagnostic object

properties.

Creation

To access block diagnostic information in a LinearizationAdvisor object, use the

getBlockInfo function. Using this function, you can obtain either a single

BlockDiagnostic object or multiple BlockDiagnostic objects. For example, see:

• “Obtain Diagnostics for Potentially Problematic Blocks” on page 17-4


• “Obtain Diagnostics Using Block Names” on page 17-5

Properties

IsOnPath — Flag indicating whether the block is on the linearization path

'Yes' | 'No'

Flag indicating whether the block is on the linearization path, specified as one of the

following:

• 'Yes' — Block is on linearization path


• 'No' — Block is not on linearization path

The linearization path connects the linearization inputs to the linearization outputs. To

view the linearization path in the Simulink model, use the highlight function.
