【摘要】 实践中应用的电磁场,其场域的边界大多数比较复杂,使解析法难以应用.虽然有些电磁问题经简化后能解析求解,但解的精度往往难以达到实践应用的要求。因此,数值计算电磁场问题成了一项重要的工作。本文用MATLAB软件编程计算二维场,方便简便并可画出图形.更直观地反映二维场的性质。更多还原

【Abstract】 Most of hte electromagnetic fields used are complex in loorders,which make it difficult to apply the analytic method. Althoosh some electromagnetic problems,ofter being simplified,can have solutions with analytis method,the accuracy can not satisfy the reqairements of pratical opplication. So it is important to use calculation sf electromagnetic fieldsproblems. The paper uses MATLAB software program to the two-dimension field,which is simple and applicable in drawing pictures,and reflects the nature of electromagnetic field more directly.更多还原
