Aunque no hay una definición precisa de matriz dispersa, podríamos definir las matrices dispersas como aquellas que tienen un número de coeficientes nulos suficientemente grande como para poder obtener ventaja de ello.

Processing of MRI data is usually performed in an array processor using the Fast Fourier Transform(FFT) algorithm. These computational requirements generally require the input data to be in a matrix whose dimensions are a power of 2, such as 128x128, 256x256, or 512x512. If the acquired k-space data does not complete this matrix, it is customary to fill in the missing cells with zeroes, a technique called zero padding, zero filling, or zero-interpolation filling(ZIP).  2, record 3, English, - zero%20filling

Analysis of Molecular Variance(AMOVA) is a method for studying molecular variation within a species. Electrophoresis, one of the most widely used methods for studying the structure of DNA, produces data of the form of 0s and 1s where 1 denotes the presence of a band and zero its absence, e. g. Sample Band A 0101... B 1000... C 0110... AMOVA works on such data to create a distance matrix between samples in order to measure the genetic structure of a population. In statistical terms, AMOVA is a testing procedure based on permutational analysis and involves few assumptions.  3, record 5, English, - analysis%20of%20molecular%20variance

A null matrix is a matrix in which every element of the matrix equals 0. It can be of any dimension. Addition and subtraction of a null matrix leaves the original matrix unchanged, multiplication with a null matrix results in another null matrix.  4, record 7, English, - zero%20matrix

The ratio of the applied excitation force phasor to the resulting velocity phasor with all other connection points of the system free, i. e. having zero restraining forces. Free impedance is the arithmetic reciprocal of a single element of the mobility matrix.  1, record 8, English, - free%20impedance

Record number: 8, Textual support number: 1 OBS

Historically, often no distinction has been made between blocked impedance and free impedance. Caution should, therefore, be exercised in interpreting published data. While experimentally determined free impedances could be assembled into a matrix, this matrix would be quite different from the blocked impedance matrix, resulting from mathematical modelling of the structure and, therefore, would not conform to the requirements for using mechanical impedance in a overall theoretical analysis of the system.  1, record 8, English, - free%20impedance

Par le passé, on a rarement fait la distinction entre impédance bloquée et impédance libre. Il faudrait donc faire attention lorsqu'on interprète les données publiées. Alors que les impédances libres déterminées expérimentalement pourraient être regroupées en une matrice, celle-ci serait tout à fait différente de la matrice d'impédance bloquée résultant de la modélisation mathématique de la structure et ne serait donc pas conforme aux exigences portant sur l'utilisation de l'impédance mécanique dans une analyse théorique globale du système.  1, record 8, French, - imp%C3%A9dance%20libre
