2223 For large matrices, Octave may not be able to display all the columns of\n\ |
|
|
2224 a given row on one line of your screen. This can result in missing\n\ |
|
|
2225 information or output that is nearly impossible to decipher, depending\n\ |
|
|
2226 on whether your terminal truncates or wraps long lines.\n\ |
|

2228 If the value of @code{split_long_rows} is nonzero, Octave will display\n\ |

2229 the matrix in a series of smaller pieces, each of which can fit within\n\ |
|

2230 the limits of your terminal width. Each set of rows is labeled so that\n\ |

2231 you can easily see which columns are currently being displayed.\n\ |
