About
Matfile is a library for reading (and in the future writing) Matlab ".mat" files.
Please note: This library is still alpha quality software and only implements a subset of the features supported by .mat files.
Feature Status
Matfile currently allows you to load numeric arrays from .mat files (all floating point and integer types, including complex numbers). All other types are currently ignored.
- [ ] Loading .mat files
- [x] Numeric arrays
- [ ] Cell arrays
- [ ] Structure arrays
- [ ] Object arrays
- [ ] Character arrays
- [ ] Sparse arrays
- [ ] Writing .mat files
Examples
Loading a .mat file from disk and accessing one of its arrays by name:
let file = std::fs::File::open("data.mat")?;
let mat_file = matfile::MatFile::parse(file)?;
let pos = mat_file.find_by_name("pos");
println!("{:#?}", pos);
Might output something like:
Some(
Array {
name: "pos",
size: [
2,
3
],
data: Double {
real: [
-5.0,
8.0,
6.0,
9.0,
7.0,
10.0
],
imag: None
}
}
)

Note that data is stored in column-major format. For higher dimensions that means that the first dimension has the fastest varying index.
ndarray support
Helpers for converting between matfile::Array and ndarray::Array can be enabled with the ndarray feature:
[dependencies]
matfile = { version = "0.5", features = ["ndarray"] }
While matfile arrays abstract over the underlying data type, ndarray
arrays are parameterized by a concrete data type. Thus the conversions
provided are fallible in case the data types are not compatible.
Examples
First, bring the TryInto trait into scope:
use std::convert::TryInto;
Dynamically dimensioned arrays
Converting a matfile array mf_arr to a dynamic dimension ndarray array
nd_arr:
let nd_arr: ndarray::ArrayD<f64> = mf_arr.try_into()?;
Statically dimensioned arrays
Converting a matfile array mf_arr to a static dimension ndarray array
nd_arr:
let nd_arr: ndarray::Array2<num_complex::Complex<f32>> = mf_arr.try_into()?;

Order: strongest tier first, then most downloads, then name, with unmeasured values last. A library counts downloads over 30 days. An app counts binary downloads per release. An app with none counts its crate downloads over 30 days. ML Rust runs this catalogue, so its closest project always gets a row.

Why ListedNo archive, New or Featured rule places it, so it is Listed.
What it lacks for Featured
- It has 3 active dependents and 2 new dependents in 365 days. Featured needs 11 active dependents or 9 new dependents in 365 days. The repository route reads 14 stars, 8 forks and 2 contributors. It needs 4,539 stars, 434 forks and 79 contributors together.
- The project is dormant and not finished. Dormancy rule
What else the check found
- The last activity is on 20 Oct 2024, 750 days ago. That reaches the 365 days the rules expect, so the project is dormant. Dormancy rule
- The oldest outside issue waits 1188 days for a reply, past the limit of 270. No maintainer replied in 365 days. Rot signals rule
Not measured: Latest release fails cargo check.
