1 Introduction

* cl-num-utils

This library implements simple numerical functions for Common Lisp, including

- =num==, a comparison operator for floats
- simple arithmeric functions, like =sum= and =l2norm=
- elementwise operations for arrays
- intervals
- special matrices and shorthand for their input
- sample statistics
- Chebyshev polynomials
- univariate rootfinding

See the sources and the docstring for more details.

All the functionality has corresponding unit tests.

** Symbol conflicts with =alexandria=

When you import both =cl-num-utils= and =alexandria=, you get symbol conflicts.  There are two solutions for this: either import only parts of =cl-num-utils= (see the packages named in each file), or shadow some symbols, eg
#+BEGIN_SRC lisp
  (cl:defpackage #:my-package
    (:use #:cl
          #:alexandria
          #:cl-num-utils)
    (:shadowing-import-from #:alexandria #:mean #:variance #:median))
#+END_SRC

** Reporting bugs

   Bugs are tracked on Github, please [[https://github.com/tpapp/cl-num-utils/issues][open an issue]] if you find one.

** Tasks
*** TODO finish histogram code, write tests
*** TODO decide whether recursive indexes are practical
code is still there, but commented out
