mat.write: Writes Matrix Data to a File
In BioPhysConnectoR: BioPhysConnectoR

Description Usage Arguments Details Value Author(s) See Also

Matrix data are written to a specified output file.

1	mat.write(mat, file.name, ij = FALSE, sym = FALSE, sparse=FALSE, formatted=TRUE)

`mat`	matrix which should be written
`file.name`	file name
`ij`	logical, if TRUE the format in the file will be: i\quad j\quad value, otherwise each row of the file represents one row in the matrix
`sym`	logical, if TRUE the matrix is symmetric, only important if `ij` = TRUE
`sparse`	logical, if TRUE the matrix is written in sparse format (e.g. only non-zero values are written to the file), only important if `ij` = TRUE
`formatted`	logical, if TRUE a blank line is inserted after all entries of one row, only important if `ij` = TRUE

In general there are two ways the output file can be written. First the matrix can be written to the file as write.table does and second the file can be written with the form: i\quad j\quad value, this means the value at position [i,j]. If the latter by ij = TRUE is selected, three more options can be chosen. If sym = TRUE the output file just contains the upper triangle and the diagonal of the matrix. If spase = TRUE only non-zero values are written. If formatted = TRUE a blank line seperates the entries of different rows.

No values are returned.
