Row equivalence — In linear algebra, two matrices are row equivalent if one can be changed to the other by a sequence of elementary row operations. Alternatively, two m times; n matrices are row equivalent if and only if they have the same row space. The concept… … Wikipedia

Matrix equivalence — In linear algebra, two rectangular m by n matrices A and B are called equivalent if for some invertible n by n matrix P and some invertible m by m matrix Q. Equivalent matrices represent the same linear transformation V → W under two… … Wikipedia
Derived row — For other uses, see Partition (disambiguation). The term partition is also French for the sheet music of a transcription. In music using the twelve tone technique, derivation is the construction of a row through segments. A derived row is a tone… … Wikipedia
