V.G. Kalmykov, T.М. Romanenko // Mathematical Machines and Systems. – 2014. – N4. – P. 79 – 85.
A new approach of fragment encoding of the halftone image, which has been applied, not as usual, on a plain surface but on a regular surface. This approach is actual in the sense of the majority of found images are applied on the surfaces, which can be considered as a plain surfaces only nominal. In this sense the image is a four-dimensional object, which is proposed to encode as two three-dimensional projections using parametrically defined spatial splines. Figs.: 5. Refs.: 5 titles.

The paper shows that reliability of results of simulation of the physical objects, which discrete model is described by a system of the linear algebraic equations (SLAE) depends not on poor-conditioned matrix but on an incorrect choice of variable SLAE at generation of equations stage by a node potential method or its analogues, and the method is a special case of a method of correct statement of a problem. It was suggested the check-out method on a correctness of SLAE, made by a node potential method, having nonsingular and a symmetric matrix and if it is necessary its transformation to a correct form.
