Dear Expert, I have some problem running Mathematica and it is taking too much time. Can you help me? Regards Swarup eqns = {AA'[x] + I*b*EE[x] + c*CC[x] + d*AA[x] == 0, BB'[x] - a*CC[x] + I*b*FF[x] - c*DD[x] + d*BB[x] == 0, CC'[x] + a*BB[x] + I*b*GG[x] + c*AA[x] + d*CC[x] == 0, DD'[x] + I*b*HH[x] - c*BB[x] + d*DD[x] == 0, EE'[x] + I*b*AA[x] - c*GG[x] - I*e*BB[x] + d*EE[x] == 0, FF'[x] - a*GG[x] + I*b*BB[x] + c*HH[x] - I*e*AA[x] + d*FF[x] == 0, GG'[x] + a*FF[x] + I*b*CC[x] - c*EE[x] - I*e*DD[x] + d*GG[x] == 0, HH'[x] + I*b*DD[x] + c*FF[x] - I*e*CC[x] + d*HH[x] == 0} ic = {AA[0] == 1, BB[0] == 0, CC[0] == 0, DD[0] == 0, EE[0] == 1, FF[0] == 0, GG[0] == 0, HH[0] == 0} DSolve[{eqns, ic}, {AA, BB, CC, DD, EE, FF, GG, HH}, x]
