Does anyone know what commands or a procedure to use to find approximate values of of eigenvalues of a random matrix in SAGE? Of any precision, but to make things simpler let's say 4.

Hope someone can help.

Thanks

Gerry

For creating random matrices, you should have a look at http://doc.sagemath.org/html/en/refer...

For computing eigenvalues, you should have a look at: http://doc.sagemath.org/html/en/const...

To work with floating-point real numbers, you should search for "real double field".

Please do not hesitate to ask for more (by providing concrete examples) if there is something unclear.
