.dmat - dense matrices¶
A .dmat file contains a dense matrix in column major order. It can contain ASCII or binary data. Note that it is uncompressed so binary only reduces the file size by 50%. But writing and reading binary is usually faster. In MATLAB, binary is almost 100x faster.
The first line is a header containing:
Then the coefficients are printed in column-major order separated by spaces.
Binary files will also contain the ascii header, but it should read:
Then there should be another header containing the size of the binary part:
Then coefficients are written in column-major order in Little-endian 8-byte double precision IEEE floating point format.
Note: Line endings must be
char(10) aka line feeds.
