Limited subset of P.C. Hansen and J. S. Jørgensen

[AIRtools](http://www2.compute.dtu.dk/~pcha/AIRtoolsII/)

Matlab suite of inversion / regularization tools, along with some ReguTools functions.

Also includes linear constrained least squares solver using cvxopt in `lsqlin.py`

More function are available in Matlab from

[AIRtools 2](https://github.com/jakobsj/AIRToolsII).

```sh

python -m pip install -e .

```

## Usage

* logmart.py: log-MART

* picard.py: Picard Plot

* kaczmarz.py  Kaczmarz ART

* maxent.py: Maximum Entropy Regularization  (from ReguTools)

* rzr.py: remove unused or little used rows from tomographic projection matrix

* lsqlin.py: linear constrained least squares solver

* matlab/logmart.m:  Implementation of log-MART

* fortran/logmart.f90: log-MART in Fortran

Examples: [tests/test_all.py](./tests/test_all.py)
