    MATLAB Calculating Eigenvalues w/ MATLAB: Defining Variables k,α,β,γ

    I use the command eig(A) to calculate the eigenvalues of the matrix A, in which k,α,β,γ are variables, A=[-0.5*k -i*α 0;-i*α -0.5*γ -i*β;0 i*β -0.5k]; eig(A) but the MATLAB shows "Undefined function or variable 'k'." I don't know how to define the variables k,α,β,γ. Can anyone tell me...
