If your model contains blocks with underlying arrays of components, the Statistics Viewer includes variables that belong to the array members.
For example, in this model, the Simscape Component block contains an underlying array of resistors.
In the Statistics Viewer, if you select a statistic with a nonzero value, the
Sources section lists all the variables that fall under this
statistic, including the array member variables. For variables that belong to the array
members, the full path to the variable in the Source column
contains the numbered name of the array member, such as
resistor(2), and so on. If the component array size is
1xN, the members are numbered
comp(N). If the array size is
NxM, the members
If you click an array member variable link in the Source column, the parent block containing the component array is highlighted in the block diagram.
