44 TI-Nspire™ Reference Guide
Note the example to the left, in which the result of getVarInfo() is
assigned to variable vs. Attempting to display row 2 or row 3 of vs
returns an “Invalid list or matrix” error because at least one of
elements in those rows (variable b, for example) revaluates to a
matrix.
This error could also occur when using Ans to reevaluate a
getVarInfo() result.
The system gives the above error because the current version of the
software does not support a generalized matrix structure where an
element of a matrix can be either a matrix or a list.
