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 lateral axis of the aircraft about which an aircraft pitches. Also called the pitch axis, normal axis, z-axis, and yawing axis.
ii. A vertical two-dimensional system of rectangular coordinates. The reference line on which distances above and below (north or south) it are marked, especially on a map, chart, or graph.

Devices with Mirror Symmetries to x- and y-Axes and Contacts Not Lying on the x-and y-Axes, at Zero Shear Stress [[sigma].sub.xy] = 0
The 1st eigenfrequency of the RWA with the isolation system is observed in a low-frequency range at around 20 Hz in the x- and y-axes, which is the same as the results obtained from the launch vibration tests.
Considering the experiments of X- and Y-axes are independent, their errors are independent, too.
In order to obtain the complex scattered field at the object plane at a distance of z = d from the measurement plane, z = 0, back-propagation is applied following the definition of the wave propagation vector in the propagation axis (z-axis), [k.sub.z], as a function of wave propagation vectors in the x- and y-axes, [k.sub.x] and [k.sub.y], as follows
Its plane is asymmetric about the x- or/and y-axes. Each floor diaphragm is rigid in its own plane and has three degrees of freedom defined at the center of mass (CM).
The [E.sub.z] fields propagating along the x- and y-axes in the TE mode are replaced by the [E.sub.x] and [E.sub.y] fields, respectively, in the TM mode.
To present the entire reflector, the x- and y-axes must first be drawn during component design to establish a cross-shaped framework.
In this AMB system, the coil on the x- and y-axes circulates the same bias current ([i.sub.b]).
The X- and Y-axes run with 3150" min and accelerate up to 12.0 m/[s.sup.2], or 1.22g.
Be sure to give your graph a descriptive title and label the x- and y-axes.
This is due to the fact that there is no propagation of necking or that chain molecules orientate to almost the same degree in both X- and Y-axes. It should be noted here that some dark areas appeared after they were previously colored.
