1 .TH BLIND-INVERT-MATRIX 1 blind 2 .SH NAME 3 blind-invert-matrix - Invert matrix-vidoes 4 .SH SYNOPSIS 5 .B blind-invert-matrix 6 [-aexyz] 7 .SH DESCRIPTION 8 .B blind-invert-matrix 9 reads a video representing a matrix from 10 stdin, inverts it, and prints the results 11 to stdout. 12 .P 13 The matrix must be at least as wide as it 14 is tall. If the matrix is wider than it is 15 tall, it is treated as an augmented matrix, 16 and the unaugmented square matrix is 17 eliminated to the identity matrix and the 18 resuling augment is printed. 19 .SH OPTIONS 20 .TP 21 .B -a 22 Ignore the alpha channel. 23 .TP 24 .B -e 25 Apply optimisation that assumes all channels 26 are identical. 27 .TP 28 .B -x 29 Ignore the first channel (the X channel). 30 .TP 31 .B -y 32 Ignore the second channel (the Y channel). 33 .TP 34 .B -z 35 Ignore the third channel (the Z channel). 36 .SH SEE ALSO 37 .BR blind (7), 38 .BR blind-multiply-matrices (1), 39 .BR blind-transpose (1), 40 .BR blind-flip (1), 41 .BR blind-flop (1), 42 .BR blind-rotate-90 (1), 43 .BR blind-rotate-180 (1), 44 .BR blind-rotate-270 (1), 45 .BR blind-rewrite-head (1) 46 .SH AUTHORS 47 Mattias Andrée 48 .RI < maandree@kth.se >
