7.3.17 ncalgebra


ncalgebra( matrix_expression C, matrix_expression D )
ncalgebra( number_expression n, matrix_expression D )
ncalgebra( matrix_expression C, poly_expression p )
ncalgebra( number_expression n, poly_expression p )
Works like nc_algebra but changes the basering.

This function is depreciated and should be substituted by nc_algebra, since it violates the general SINGULAR policy: only ring and setring can change the basering. More concretely, replace by def A = nc_algebra(C, D); setring A; which will additionally introduce a new ring. Afterwards, some objects may have to be mapped into the new ring.

See also nc_algebra; nctools_lib.
