Matrix Conversions

This tool is useful for basic matrix operations:

• Transposing the input matrix matrix.
• Computing the support matrix of the input matrix.
• Computing the signed support matrix (negative entries are turned into \( -1 \)'s, positive into \( +1 \)'s) of the input matrix.
• Computing a Camion-signed version of the input matrix.

Usage

The executable cmr-convert-matrix copies the input matrix, potentially applying operations.

./cmr-convert-matrix [OPTION]... FILE

Options:

• -i FORMAT Format of input FILE; default: dense.
• -o FORMAT Format of output matrices; default: dense.
• -t Output the transposed matrix (can be combined with other operations).
• -s Create the support matrix instead of copying.
• -s Create the signed support matrix instead of copying.
• -c Creates the Camion-signed version instead of copying.
• -d Use double arithmetic.

Formats for matrices are dense-matrix and sparse-matrix. If FILE is -, then the input will be read from stdin.
