大家好,乐天来为大家解答以下的问题，关于贝塞尔函数表，贝塞尔函数这个很多人还不知道,现在让我们一起来看看吧！
1、syms a k b v1 v2 D1 D11 D12 k1>> H11 =besselj(0,k*a);>> H12 =bessely(0,k*a);>> H13 =besseli(0,k*a);>> H14 =besselk(0,k*a);>> H15=0;H16=0;>> H21=diff(H11);>> H22=diff(H12);>> H23=diff(H13);>> H24=diff(H14);>> H25=0;>> H26=0;>> H31 =besselj(0,k*b);>> H32 =bessely(0,k*b);>> H33 =besseli(0,k*b);>> H34 =besselk(0,k*b);>> H35 =-besselj(0,k1*b);>> H36 =-besseli(0,0.k1*b);>> H41 =diff(H31);>> H42 =diff(H32);>> H43 =diff(H33);>> H44 =diff(H34);>> H45 =diff(H35);>> H46 =diff(H36);>> H51=-D1*diff((diff(H31,b,2)+1/b*diff(H31,b)),b);>> H52=-D1*diff((diff(H32,b,2)+1/b*diff(H32,b)),b);>> H53=-D1*diff((diff(H33,b,2)+1/b*diff(H33,b)),b);>> H54=-D1*diff((diff(H34,b,2)+1/b*diff(H34,b)),b);>> H55=(D11+D12)*diff((diff(-H35,b,2)+1/b*diff(-H35,b)),b);>> H56=(D11+D12)*diff((diff(-H36,b,2)+1/b*diff(-H36,b)),b);>> H61=-D1*(V1/b*diff(H31,b)+diff(H31,b,2));>> H62=-D1*(V1/b*diff(H32,b)+diff(H32,b,2));>> H63=-D1*(V1/b*diff(H33,b)+diff(H33,b,2));>> H64=-D1*(V1/b*diff(H34,b)+diff(H34,b,2));>> H65=(D11+D12)*diff(-H35,b,2)+(D11*V1+D12*V2)/b*diff(-H35,b);>> H66=(D11+D12)*diff(-H36,b,2)+(D11*V1+D12*V2)/b*diff(-H36,b);>> A=[H11 H12 H13 H14 H15 H16; H21 H22 H23 H24 H25 H26; H31 H32 H33 H34 H35 H36; H41 H42 H43 H44 H45 H46; H51 H52 H53 H54 H55 H56; H61 H62 H63 H64 H65 H66]solve(det(A));。
