liboctave: confirm that matrices constructors are limited to 2 dimensions. * liboctave/array/boolMatrix.h, liboctave/array/chMatrix.h (boolMatrix::boolMatrix(dim_vector),boolMatrix::boolMatrix(dim_vector,bool), charMatrix::charMatrix(dim_vector),charMatrix::charMatrix(dim_vector,char)): call redim(2) on the dim_vector argument to the constructor, the same that happens in the other typeMatrix classes. * liboctave/array/fCMatrix.h: simplify code to reshape NDArray input into matrix form (should have no effect).
