# hMaps -- list the maps h(p): A_0(p)--> A_1(p) in a matrixFactorization

- Usage:
    `hMaps = hMaps mf`
- Inputs:
  - mf, a list, output of a matrixFactorization computation
- Outputs:
  - hMaps, a list, list matrices $h_p: A_0(p)\to A_1(p)$. The sources and targets of these maps have the components B_s(p).

## Description

See the documentation for matrixFactorization for an example.

- dMaps -- list the maps d(p):A_1(p)--> A_0(p) in a matrixFactorization
- BRanks -- ranks of the modules B_i(d) in a matrixFactorization
- bMaps -- list the maps d_p:B_1(p)-->B_0(p) in a matrixFactorization
- psiMaps -- list the maps psi(p): B_1(p) --> A_0(p-1) in a matrixFactorization

## Ways to use hMaps:

- `hMaps(List)`

## For the programmer

The object hMaps is a method function.
