solving Singular value equations

syms A1 A2 A3 A4
Solution= solve ((A1+(0*A2)+A3+(0*A4))),(0*A1)+(alpha_r*A2)+(0*A3)+(beta_r*A4),(A1*cos(alpha_r*L))+(A2*sin(alpha_r*L))+(A3*cosh(beta_r*L)+(A4*sinh(beta_r*L))),(-(A1*(alpha_r*sin(alpha_r*L))))+A2*(alpha_r*cos(alpha_r*L))+ (A3*beta_r*sinh(beta_r*L))+(A4*beta_r*cosh(beta_r*L))

I want to solve the above eqn for the unknown coeff. A1... A4.

I am getting following error,
??? Error using ==> svd
Input to SVD must not contain NaN or Inf.

Error in ==> pinv at 29
[U,S,V] = svd(A,0);

Also, I tried using matrix method, still getting the same error.

If you have some idea, please share me,

Thanks
