Eigenvalue calculator is an online tool to determine the eigenvalues of a square matrix. To do this calculation, we have to consider the unit matrix of same order. Eigenvalues are denoted by λ. The detailed step is described in the next section.

Following steps are used to calculate the eigenvalues of a given matrix.

Step1: Label the given matrix as A.

Step2: Consider a unit matrix same as the order of A.

Step3: We have to find out the values of λ which satisfy the characteristic equation of the matrix A. For that determine λI and then A-λI.

Step4:
Then find the value of λ, if det(A-λI)=0.
