Check ID: mathworks.hism.hisl_0066

Description

This check identifies the Gain blocks with value that resolves to 1, an identity matrix, or a matrix of ones.

Available with Simulink® Check™.

Results and Recommended Actions

ConditionRecommended Action
One or more Gain blocks in the model resolve to 1 or an identity matrix.Remodel the Gain blocks so that the gain value does not resolve to 1, an identity matrix, or a matrix of ones.
