# spectral-norm description

## Background

MathWorld: "Hundred-Dollar, Hundred-Digit Challenge Problems", Challenge #3.

Thanks to Sebastien Loisel for suggesting this task.

## How to implement

We ask that contributed programs not only give the correct result, but also **use the same algorithm** to calculate that result.

Each program should:

calculate the spectral norm of an infinite matrix A, with entries a

_{11}=1, a_{12}=1/2, a_{21}=1/3, a_{13}=1/4, a_{22}=1/5, a_{31}=1/6, etcimplement 4 separate functions / procedures / methods like the C# program

**diff** program output N = 100 with this output file to check your program output has the correct format, before you contribute your program.

Use a larger command line argument (5500) to check program performance.
