x-y matrix

A group of rows and columns. The x-axis is the horizontal row, and the y-axis is the vertical column. An x-y matrix is the reference framework for two-dimensional structures, such as mathematical tables, display screens, digitizer tablets, dot matrix printers and 2D graphics images.

i. The longitudinal axis of an aircraft around which the aircraft rolls and banks. Also called a rolling axis.
ii. The horizontal axis in a system of rectangular coordinates. The line on which distances to the right or the left (east or west) of the reference line are marked, especially on a map, chart, or graph.

The thrust and torque of both X-axis motors converge to provide twice the thrust of a single motor in the Z-axis while the absence of a motor in the Z-axis eliminates the need for cable tracks and expensive, flexible cable" says Ed Long, IntelliAxis[TM] product manager.
Refer to the new x-axis values as [x.sub.2]- axis values.
The vibration periods [T.sup.wo.sub.xj] and [T.sup.wo.sub.yj], i = 1, 2, are the results of the specimen without water, corresponding to the first two modes along x-axis and y-axis, respectively.
In the application of this coordinate system during the presigmoid approach, we recommended that the X-axis and Y-axis should be outlined and the site of the ASTS should be marked on the scalp according to the data shown in [Table 1] before disinfection and draping of the operation area.
The geomagnetic field is taken to be F = 5 x [10.sup.4] nT, with dip angle I = [pi]/4 and the angle from the magnetic north to the x-axis is [eta] = [pi]/18.
Starting at the left end of the x-axis, place 21 short pieces of tape on the string.
All base frame designs have extra available stroke in the X-axis to accommodate full coverage of optional 32mm boring units.
Common errors included inferring the relative value of the mean according to the center of the x-axis rather than the center of the distribution of data, identifying histograms with greater heights as those having the greater standard deviations, and interpreting skewness as a shift of the center of the distribution along the x-axis rather than an asymmetry of the distribution.
The images fit onto graphs with an x-axis and a y-axis, where each point on the graph is given by two numbers, or coordinates.
Historically, Arthur notes, evolution has been envisioned primarily along either an x-axis or a y-axis.
(Hint: The "day" will go on the x-axis, and the water amount will go on the y-axis.)
We begin with a blank x-y chart where complexity increases along the vertical y-axis and goodness along the horizontal x-axis. Goodness is a general term that means slightly different things depending on the application and context.
