Description

The last entry in Table 7-3 (Specification of MatrixID according to SizeID, prediction type and colour component) is

|3|Inter|Y|1|

it looks like the last value (1) should be 3.

I think that the initial value (1) is right as referred tables are 2D or 3D and you have to consider the duet (SizeID, MatrixID) for array addressing purposes (Cf. addressing of 7.4.2.5 syntax elements to help understanding).
Besides this table may be extended, in a second time, to help in supporting fidelity range extensions (Cf. JCTVC-J0078).

I agree with Pierre that for sizeId equal to 3 (32x32, currently we only have 32x32 luma transform blocks ) there are two matrices: 0 and 1 whereas 0 is used for Intra Y and 1 is used for Inter Y.
