.SH DESCRIPTION |
| 24 |
|
.I Rmtxop |
| 25 |
< |
loads and concatenates (multiplies) or adds together component matrix files |
| 26 |
< |
given on the command line. |
| 25 |
> |
loads and concatenates or adds/multiplies/divides |
| 26 |
> |
together component matrix files given on the command line. |
| 27 |
|
Each file must have a header containing the following variables: |
| 28 |
|
.sp |
| 29 |
|
.nf |
| 96 |
|
to the same input matrix. |
| 97 |
|
.PP |
| 98 |
|
If present, the second and subsequent matrices on the command |
| 99 |
< |
line are concatenated to the result unless separated by a plus ('+') symbol, |
| 100 |
< |
in which case the elements are added together. |
| 99 |
> |
line are concatenated to the result unless separated by a plus ('+'), |
| 100 |
> |
asterisk ('*'), or forward slash ('/') symbol, |
| 101 |
> |
in which case the matrix elements are added, multiplied, or divided together, |
| 102 |
> |
respectively. |
| 103 |
> |
(Note that the asterisk must be quoted or escaped in most shells.)\0 |
| 104 |
> |
In the case of addition, the two matrices involved must have the same number |
| 105 |
> |
of components. |
| 106 |
> |
For element-wise multiplication and division, the second matrix is |
| 107 |
> |
permitted instead to have a single component per element, which will be |
| 108 |
> |
applied equally to all components of the first matrix. |
| 109 |
> |
If element-wise division is specified, any zero elements in the second |
| 110 |
> |
matrix will result in a warning and the corresponding component(s) in the |
| 111 |
> |
first matrix will be set to zero. |
| 112 |

.PP |
| 113 |
|
The number of components in the new matrix after applying any |
| 114 |
|
.I -c |
| 115 |
|
transform must agree with the prior result. |
| 117 |
|
in the prior result must equal the number of rows in the new matrix, and |
| 118 |
|
the result will have the number of rows of the previous and the number |
| 119 |
|
of columns of the new matrix. |
| 120 |
< |
In the case of addition, the number of rows and columns of the prior |
| 121 |
< |
result and the new matrix must match, and will not be changed by the |
| 122 |
< |
operation. |
| 120 |

In the case of addition, multiplication, and division, |
| 121 |
> |
the number of rows and columns of the prior result and the |
| 122 |
> |
new matrix must match, and will not be changed by the operation. |
| 123 |

.PP |
| 124 |
|
Results are sent to the standard output. |
| 125 |
|
By default, the values will be written in the lowest resolution format |
