Here is the correct elements of the 6 by 6 matrix. Once again the values are not numeric

Consider the matrix [A]= [a_ij ] defined below

Note that n_s =eta[s],  η_r = eta[r], η_i = eta[i], α₁ = alpha [1], σ₁ = sigma [1],  σ₂ = sigma [2], φ₂ = phi[2], ω₂ = Omega [2], P₁ = P [1], P₂ = P [2], M₁ = M [1], M₂ = M [2]

a11 = -E+n_{s  ,}   a12=F-α₁ , a13=G-α₁, a14=0, a15= -mλξ,  a16=0

a21 =0,  a22 = -H₁+η_s , a23=0, a24=0, a25= mλξ,  a26=0

a31 =0,  a32 = σ₁ , a33=-L+η_s, a34=0, a35= 0,  a36=0

a41 =0,  a42 = -η_i/m , a43=-η_r/m, a44=-M₁, a45=-P₁+φ₂,  a46=-P₂+ω₂

a51 =0,  a52 = η_i/m , a53=0, a54=0, a55=cβ-H₂,  a56=c′β′ (not derivatives, you can use the exclamation marks)

a61 =0,  a62 =0 , a63=η_r/m, a64=0, a65=α₂,  a66=-M₂

Please I will be glad if you can still run the eigen values for me again.

The error I now recieve is [Length of output exceeds limit of 1000000]

Is there no any solution to this?

Till I hear from you.

Thanks

Here is the values of the 6 X 6 matrix (The values are not numbers (that is not numeric), rather the contain symbolic parameters.. Consider the matrix [A] defined below

a11 = -E+n_{s  ,}   a12=F-α₁ , a13=G-α₁, a14=0, a15= -mλξ,  a16=0

a21 =0,   a22 = -H₁+η_s , a23=0, a24=0, a25= mλξ,  a26=0

a31 =0,   a32 = σ₁ , a33=-L+η_s, a34=0, a35= 0,  a36=0

a41 =0,   a42 = -η_i/m , a43=-η_r/m, a44=-M₁, a45=-P₁+φ₂,  a46=-P₂+ω₂

a51 =0,   a52 = η_i/m , a53=0, a54=0, a55=cβ-H₂,  a66=c′β′

a61 =0,   a62 =0 , a63=η_r/m, a64=0, a65=α₂,  a66=-M₂

I need the Determinant, trace and eigen values. The problem is that I do have an error message when I want to find the eigenvalues.

I will be glad to find the eigen values. Hoping to hear from you.

Thanks
