ERR:DIM MISMATCH Error
Your TI-84 Plus displays the
ERR:DIM MISMATCH error if you are trying to perform an operation
that references one or more lists or matrices whose dimensions do not match. For example,
multiplying L1*L2, where L1={1,2,3,4,5} and L2={1,2} produces an
ERR:DIM MISMATCH error
because the number of elements in L1 and L2 do not match.
ERR:INVALID DIM Error
The
ERR:INVALID DIM error message may occur if you are trying to graph a function that does not
involve the stat plot features. The error can be corrected by turning off the stat plots. To turn the
stat plots off, press y , and then select
4:PlotsOff.
