If the message appears when you try to graph functions deactivate the statistical plots. To do so:

Press [2nd][Y=] to access (STAT PLOTs)
Select [4:PlotsOff] then [ENTER]

That should solve your problem. Post a comment to this thread if you still have trouble graphing.

If the message appears in another context, it sure would help knowing the context of the error.

SOURCE: TI-83 Plus Calculator: what does ERR: DIM MISMATCH mean?...

Imagine you are doing statistical calculations with two list, say L1 and L2 but one list has 10 elements (values) while the other has only 9. The dimension of the lists are different (mismatched) because one is 10 and the other 9.

Another case is if you are manipulating matrices such as adding a3x3 matrix to 3x2 matrix. Both matrices have the same number of rows but different numbers of columns.

SOURCE: For ti 84+ HOW do I solve the error indication

Certain mathematical entities have so called dimensions: A list has a dimension, which is the number of elements in the list. Matrices also have dimensions which are the number of rows, and the number of columns.

If you are doing paired variable statistics, the data is in two lists and if the number of elements in one list is not equal to the number of elements of the the other, the dimension are not matched (equal), and calculator will give you dimension mismatch in any calculation that involves BOTH list.

The problem with your question is that you do not say what you were trying to do and I will have to guess or read your mind.

I suggest you reset the RAM to erase any old configuration that may be interfering with what you want to do.

  1. Press [2nd] [+] to access (MEM)ory management.
  2. Press [7:Reset][1:All ram][2:Reset]
  3. Calculator answers with "Ram Cleared" message.
  4. Press [CLEAR] to erase the message.
  5. Restart what you were doing (statistics, or graphs)

SOURCE: Whenever I try to graph something on my TI-84 plus

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

What does Dim Mismatch on TI-83 mean?


You have a dimension mismatch if (for example) you are doing 2-var stats and the two lists do not have the same length. You can also have mismatch with matrices.

I get a ERR: DIM MISMATCH when I try to use graph an inequality using the inequalz app


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

That is a piece of cake. just go to the two Lists that you are using for the equation and see if they are the same length.

Dim Mismatch


That is because you don't have the right amount of points. Either delete one point or add another point. Then try to graph it.

Dim Mismatch


Hit 2nd then the Y= button and you'll get to the stat plots. make sure they are all turned off, sometimes random programs (ie. games) will turn on stat plots and screw up your other programs and graphs.
