matlab-jnifti binary package in Ubuntu Jammy amd64

 The JNIfTI toolbox includes a stand-alone NIfTI-1/2 parser that works on both
 MATLAB and GNU Octave without needing additional components. To just reading
 and writing the un-compressed NIfTI and Analyze7.5 files (.nii, .hdr/.img),
 one only needs to run addpath('/path/to/jnifti'). For MATLAB, JNIfTI toolbox
 utilizes memmapfile-based disk-reading, making it very fast. For Octave,
 memmapfile is currently not implemented, so, a full reading is required.
 .
 The JNIfTI toolbox is also capable of reading/writing gzip-compressed NIfTI
 and Analyze7.5 files (.nii.gz, .hdr.gz, .img.gz). This feature is supported
 in MATLAB directly without needing another toolbox (MATLAB must be in the
 JVM-enabled mode).
 .
 To process gzip-compressed NIfTI/Analyze files in Octave and MATLAB with
 -nojvm, one need to install the open-source JSONLab and ZMat toolboxes
