MFL (MAT File Library)

0.5.15

  • added support for ignoring undocumented sections introduced by R2023b (thanks @nedtwigg)

0.5.14

  • added a workaround for reading faulty char arrays

0.5.13

  • added extension support for Mat5Reader (thanks @MieszkoMakuch)

0.5.12

  • added support for mcos version 5 introduced in R2022b (thanks @nedtwigg)

0.5.11

  • added support for mcos version 4 introduced in R2022b (thanks @nedtwigg)

0.5.10

  • added custom allocator support to char arrays (fixes #69)

0.5.9

  • Improved error message for v7.3 files

0.5.8

  • Fixed an overflow issue when reading variables that are >1GB compressed (fixes #65).

  • Changed rules to allow reading of 2-4 GB variables (fixes #64). Note that MATLAB has a 2 GB write limit, but it can read 4 GB variables saved by Octave.

0.5.7

  • Removed the special subsystem entry from the content list to avoid confusing users

  • Changed EJML Scope to provided

  • Fixed a bug where EJML’s CMatrixRmaj was stored as ZMatrixRmaj

  • Added functionality to automatically determine EJML matrix based on data type

0.5.6

  • Fixed default endian-ness for writing to memory mapped files (fixes #58)

  • Fixed a bug that caused disk access to fail on Android (fixes #56)

  • Disabled unsafe access for ARM platforms to avoid potential unaligned access issues

0.5.5

  • Fixed bug that caused the struct index map to be wrong after field removal (fixes #53, thanks @ryanlb1000)

  • Added size checks to prevent variables >2GB from being serialized. (fixes #55, thanks @syr)

  • Removed Java8 hash methods. (fixes #51)

0.5.4

  • Improved string display for function handles and Java objects

  • Fixed a subsys-related bug that caused issues when reading mat files in Octave. Thanks @grabarczyk-t

0.5.3

  • Fixed a bug that caused some sparse matrices to fail (nzMax > numNz). Thanks @mephenor

  • Added getNumNonZero() to sparse interface and deprecated getNzMax(). This is equivalent to MATLAB’s nnz.

0.5.2

  • Improved streaming source fallback for files that are larger than 2GB and can’t be memory mapped. The FileInputStream wrapper was changed to using buffered IO via FileChannel / ByteBuffer.

  • Removed hyphens from Jigsaw module name. Thanks @stffnjng

  • Added convenience methods to Mat5 for reading from and writing to disk

0.5.1

  • Removed resources (changelog, license, etc.) from generated jar to avoid issues with e.g. ProGuard trying to copy them into the uber jar

  • Fixed an issue when reading empty sparse matrices from R2018b due to an undocumented format change

  • Fixed writing empty MatrixSparseCSC EJML types

0.5

  • Renamed maven coordinates and Jigsaw module names

Mat-File IO (previous name)

0.4.1

  • Added parser support for v3 MCOS subsystems. (Note: The v2 parser seems to handle v3 just fine, but we don’t actually know where the differences are). Thanks @nedtwigg

0.4

This change breaks backwards compatibility with 0.3 for some corner case use cases.

  • Removed Array::isGlobal()

  • Moved NamedArray to MatFile.Entry

  • Added MatFile.Entry::isGlobal()

  • Added MatFile::addEntry(entry)

  • Added Mat5Writer::writeEntry(entry)

  • Renamed Mat5Reader::setArrayFilter(ArrayFilter) to Mat5Reader::setEntryFilter(EntryFilter)

  • Added extension module for converting EJML matrices

  • Added Sinks::newStreamingFile(file, append) to add entries to existing MAT files

0.3

  • Added hashCode() and equals() to all Arrays. Thanks @nedtwigg

  • Fixed a bug that caused the global flag to be ignored during construction. Thanks @nedtwigg

  • Fixed a bug that caused field names inside structs and objects to be serialized incorrectly

0.2

  • Moved common.util to mat.util

  • Removed unused utilities

  • Removed multi-release jar dependency due to lack of support for some build tools (e.g. obfuscation)

  • Improved streaming file sink implementation

  • Changed StreamingDoubleMatrix2D to be a test example

  • MatFile API

    • Renamed size() to getNumEntries()

    • Added clear()

    • Added getEntries() for accessing Iterable<NamedArray>

0.1.2

  • fixed binary incompatibilities with Java 6 that were introduced by compiling with JDK 9

0.1.1

  • added license headers to all files

0.1

  • initial release
