Crate matfile

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("tests/double.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.

Structs

Array	A numeric array (the only type supported at the moment).
MatFile	MatFile is a collection of named arrays.

Enums

Error
NumericData	Stores the data of a numerical array and abstracts over the actual data type used. Real and imaginary parts are stored in separate vectors with the imaginary part being optional.
