Singular Manual: ncalgebra

| ### 7.3.17 ncalgebra `Syntax:` `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 `)` `Type:` none `Purpose:` Works like nc_algebra but changes the basering. `Remark:` 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.
