|
the number of columns specified by the |
| 33 |
|
.I \-oc |
| 34 |
|
option. |
| 35 |
+ |
The number of rows may be specified with a |
| 36 |
+ |
.I \-or |
| 37 |
+ |
option, or may be determined automatically from the size of the input if |
| 38 |
+ |
it is an even multiple of the number of columns (as it should be). |
| 39 |
+ |
Alternatively, both may be specified using a |
| 40 |
+ |
.I \-o |
| 41 |
+ |
option with the number of rows and columns separated by an 'x', as in "30x14" |
| 42 |

for 30 rows by 14 columns. |

.I Rcollate |

can also reorder the input into nested blocks by continuing the output size |
| 45 |
+ |
string. |
| 46 |
+ |
For example, "3x10X7x2" would order output data with a 3x10 super-array of |
| 47 |
+ |
7x2 subblocks. |
| 48 |
+ |
This type of block hierarchy is convenient for visualizing tensor data. |

.SH EXAMPLES |

|
To change put 8760 color triplets per row in a matrix with no header: |
| 132 |
|
.IP "" .2i |
| 133 |
|
rcollate -h \-oc 8760 input.dat > col8760.dat |
| 135 |
|
To transpose a binary file with 145 float triplets per input row: |
| 136 |
|
.IP "" .2i |
| 137 |
|
rcollate -ff3 -ic 145 -t orig.flt > transpose.flt |
| 138 |
+ |
.PP |
| 139 |
+ |
To create an appropriate header for a binary float matrix as required by |
| 140 |
+ |
.I rmtxop(1)\: |
| 141 |
+ |
.IP "" .2i |
| 142 |

rcollate -hi -ff3 -or 145 -oc 8760 input.smx | rmtxop dcoef.dmx - > res.txt |

To visualize a Shirley-Chiu BTDF matrix where the interior resolution is |
| 145 |

64x64 and the exterior resolution is 32x32: |
| 146 |
