How about general rotations?

[AFLuo]

Existing rotation methods for heint includes RotateColumnsNew and RotateRowsNew to rotate columns and rows respectively, which is quite strange since such rotation methods put restrictions on dimensions. I wonder if i can rotate as if there is only one row.
Take an example, I have a vector, which contains params.N() elements, and i want to rotate over the ct encrypting this vector.
It seems that existing rotation methods does not support this operation.

@AFLuo, the plaintext domain for batched vectors in BFV and BGV is Z_t^{2 * N/2}, i.e. a matrix of dimension 2 x N/2 with coefficients modulo t. Rotations are defined on the rows and columns of this matrix. So what you are asking for is not possible because the plaintext algebra does not allow it.

Got it, thank you very much
