How do I multiply matrices?

How can I store a multidimensional array in a DBM file?

(PERL predefined variable) $SUBSCRIPT_SEPARATOR The subscript separator for multidimensional array emulation.

perl5 module to print arrays of elements in sorted columns. p5-Array-PrintCols-2.1 Perl5 module to print arrays of elements in sorted columns

p5-Data-ShowTable-3.3 perl5 module to pretty-print arrays of data

ShowTable - Pretty-prints arrays, converting from columnar ASCII data. In the Array/ directory. Also see Array::PrintCols above. [Perl] {oss}

Math::Matrix - Matrix functions: multiply, invert, transpose, solve. Each matrix is an array of array references, as you'd expect: the middle element of a 2x2 array is $array[1][1]. [Perl] {oss}

Math::MatrixReal - Provides a slew of matrix operations optimized for real numbers. Simpler but less featureful than PDL. [Perl] {oss}

Math::VecStat - Basic numeric operations on vectors, e.g. min(), sum(), average(). [Perl] {oss}
