Calculate eigenvalues and eigenvectors

On this site one can calculate the Characteristic Polynomial, the Eigenvalues, and the Eigenvectors for a given matrix. →Below is a calculator to determine matrices for given Eigensystems.

Input the components of a square matrix separating the numbers with spaces.
The new script recognizes fractions and complex numbers, e.g., -3+7/5i (input without spaces!)
The exact modus is implemented in Javascript too, but is not very fast for bigger matrices. Better use the Java modes.

characteristic polynomial

Output format   dezimal separator:
Gerschgorin circles       resp. sum of rows
... columns
            plot all elements

• eigenvalues,   • diagonal entries,   • other entries of matrix

Calculation of a matrix for given Eigenvalues and vectors

Input by the line: Eigenvalue, components of the correspondent Eigenvector, all separated with spaces.
Use / for fractions, input complex numbers like 1/2-3/7i
