## Installing
```julia
julia> ]
pkg> add HarwellRutherfordBoeing
pkg> test HarwellRutherfordBoeing
```
## Obtaining the Harwell-Boeing Collection
Retrieve the systems from the [Harwell-Boeing Collection](https://math.nist.gov/MatrixMarket/data/Harwell-Boeing/).
## Obtaining Matrices and Supplementary Data in Rutherford-Boeing Format
The best source is the [University of Florida Sparse Matrix Collection](https://sparse.tamu.edu/).
## Example
```julia
using HarwellRutherfordBoeing
M = HarwellBoeingMatrix("well1850.rra")
```
```julia
Harwell-Boeing matrix WELL1850 of type RRA
1850 rows, 712 cols, 8758 nonzeros
1 right-hand sides, 0 guesses, 0 solutions
```
```julia
M.matrix
```
```julia
