- DIVAMatrixExport void ToMatlab(const CDString& sFilename, const CDString& sName, const CDString& sComment, bool fAppend) const
-
Writes the vector to disk in MatLab (.m) format.
To read the vector into MatLab write e.g.
'my_vector.m' at the MatLab prompt.
Notice that this should be used for storage a (really)
large vectors, due to the computational and i/o overhead
induced by the simple MatLab text format.
Also, remember that MatLab can't read (.m) files with lines
longer than 4096 bytes.
If no communication with MatLab is needed, but merely
to/from disk functionality within a DIVA program, it is
suggested to use the fast binary i/o methods ToFile() and
FromFile().
- Parameters:
- sFilename - Output file name. Should have the extension '.m'.
sName - Name of destination matlab variable.
sComment - Optional comment inside the file.
fAppend - If true, the vector is appended to the file
'sFilename'.
