Just as the invention of photography challenged the world's visual literacy at the turn of the century, so has computer graphics begun to reshape visual communication. Although still in its infancy, recently developed tools for visual communication have made computer graphics and electronic imaging accessible to a much larger number of artists and other professionals. The use of these systems h...
با استفاده روش تکراری ?-بلوکی sor را برای حل دستگاه ax = b که در آن a یک ماتریس مختلط m*n با شرط m بزرگتر مساوی n و رتبه ماتریس a کمتر مساوی n می باشد a را تجزیه وروش تکراری aor به کار می بریم.و بعد شبه همگرایی روشهای aor , jor را مورد بررسی قرار می دهیم. و در نهایت شرایط لازم و کافی را برای شبه همگرایی توسعه می دهیم.وپارامتر بهینه و فاکتور پیوسته همگرایی روش را به دست مل آوریم.
