A maximum length sequence (MLS) generator

File Information
Description

Maximum length sequences (MLS) are used to probe systems for errors or transfer functions (e.g., as in LTI systems). An initial register sequence of ones is generated (instead of a random binary sequence) by default, but a random sequence can be used. This code makes use of the gfprimdf.m to produce the primitive polynomial (requires the Communications tool box).

Updates to allow fast generation of sequence up to order 26.

Corrected some minor comment mistakes.

Fixed a small error where it would save a 15th order sequence to file instead of storing in the workspace.
