[MATLAB调试笔记]Update magnetic field in one step
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
function [field] = bfield(field,prm)% Update magnetic field in one stepX2 = prm.X2;f = field; % reference to Field objf.by(X2) = f.by(X2) + f.ez( X2) - f.ez(X2-1);f.bz(X2) = f.bz(X2) - f.ey(X2+1) + f.ey(X2 );f.by(prm.nxp2)= f.by(2);%對(duì)稱邊界條件f.bz(prm.nxp2)= f.bz(2);f.by(1) = f.by(prm.nxp1);f.bz(1) = f.bz(prm.nxp1);
