.TH BLIND-INVERT-MATRIX 1 blind .SH NAME blind-invert-matrix - Invert matrix-vidoes .SH SYNOPSIS .B blind-invert-matrix [-aexyz] .SH DESCRIPTION .B blind-invert-matrix reads a video representing a matrix from stdin, inverts it, and prints the results to stdout. .P The matrix must be at least as wide as it is tall. If the matrix is wider than it is tall, it is treated as an augmented matrix, and the unaugmented square matrix is eliminated to the identity matrix and the resuling augment is printed. .SH OPTIONS .TP .B -a Ignore the alpha channel. .TP .B -e Apply optimisation that assumes all channels are identical. .TP .B -x Ignore the first channel (the X channel). .TP .B -y Ignore the second channel (the Y channel). .TP .B -z Ignore the third channel (the Z channel). .SH SEE ALSO .BR blind (7), .BR blind-multiply-matrices (1), .BR blind-transpose (1), .BR blind-flip (1), .BR blind-flop (1), .BR blind-rotate-90 (1), .BR blind-rotate-180 (1), .BR blind-rotate-270 (1), .BR blind-rewrite-head (1) .SH AUTHORS Mattias Andrée .RI < maandree@kth.se >
