# Line 5 | Line 5 | rcollate - resize or transpose matrix data

# Line 29 | Line 31 | the number of columns specified by the
31   .I \-oc
32   option.
33   By default, the file is assumed to include an information header, which
34 < is copied to the standard output along with the command name, but the
34 > is copied to the standard output along with the command name.
35 > The
36 > .I \-hi
37 > option may be used to turn off the expectation of a header on input.
38 > The
39 > .I \-ho
40 > option turns off header output, and
41   .I \-h
42 < option may be used to turn this behavior off.
42 > by itself turns off both input and output headers.
43 > The
44 > .I \-w
45 > option turns off non-fatal warning messages, such as unexpected EOD.
46   .PP
47   The input format is assumed to be ASCII, with three white-space separated words
48   (typically numbers) in each record.
# Line 64 | Line 75 | Note that the lack of row separators in binary files m
75   does not actually do anything for binary files unless the transpose
76   option is given, also.
77   .PP
78 + If an input header is present, it may contain the format, number of components
79 + and matrix dimensions.
80 + In such cases, the
81 + .I \-ic,
82 + .I \-ir
83 + and
84 + .I \-f
85 + options are not required, but will be checked against the header
86 + information if provided.
87 + .PP
88   The transpose option,
89   .I \-t
90   swaps rows and columns on the input.
# Line 83 | Line 104 | For large transpose operations on Unix systems, it is
104   to specify the input file on the command line, rather than reading
105   from the standard input, since
106   .I rcollate
107 < can map the file directly into memory.
107 > can map the file directly into virtual memory.
108   .SH EXAMPLE
109   To change put 8760 color triplets per row in a matrix with no header:
110   .IP "" .2i
