# scalar

الإنجليزية - الإنجليزية
An amplifier whose output is a constant multiple of its input
A quantity that has magnitude but not direction; compare vector
Having magnitude but not direction
Of, or relating to scale
A number Usually used in contexts where there are also vectors around, or functions Examples of usage: "the length of a vector is a scalar;" "-3 sin x is a scalar multiple of sin x "
A dimensionless value 5, 2 14, -1e20 are all scalar values See vector
a physical quantity which can be specified by a single numerical value, including the unit (Strictly the value must be the same in all reference frames or coordinate systems that are not moving relative to one another ) Most electrical quantities including charge, potential and emf, are scalars Electric field and magnetic filed are not scalars - they are vector quantities
of or relating to a directionless magnitude; "scalar implicatures"
A measure that only has magnitude, e g , time and temperature
In the quaternion analysis, a quantity that has magnitude, but not direction; distinguished from a vector, which has both magnitude and direction
A quantity that scales, or adjusts size; a single number
A physical variable which can be uniquely specified by giving a magnitude (number) and a unit
NCL: A single element of data of any type is referred to as a scalar value
(1) A quantity characterized by a single value (I) (A) (2) Contrast with vector
A quantity that has magnitude only
A value with no user-visible components
A single value, be it a number or a string Regular variables are scalars; arrays and functions are not
a variable quantity that cannot be resolved into components
(n ) a single datum that is not an array; or (adj ) not having the property of being an array
A physical quantity that involves magnitude, but not direction Examples are speed, temperature, and pressure Quantities that also involve direction, such as velocity, are called vectors
A real number
A number with units For example, speed, temperature, distance, and time are scalars
{s} of or pertaining to a scalar
– a physical quantity that can be completely specified by its magnitude alone
Pertaining to data items with a rank of zero A single data object of any intrinsic or derived data type Contrast with array See also rank-one object
{i} (Mathematics, Physics) quantity with magnitude and no direction
An arithmetic object, or a pointer to an object of any type
style or motive of music based on a scale
A data value (number); for example, element a[4] of an array or the value of the variable X
Any physical quantity whose field can be described by a single numerical value at each point in space
A quantity that has a size or magnitude but no direction For example, any real number is a scalar
An arithmetic object, or a pointer, or a reference to an object of any type
a variable quantity that cannot be resolved into components of or relating to a directionless magnitude; "scalar implicatures
Any physical quantity whose field can be described by a single numerical value at each point in space A scalar quantity is distinguished from a vector quantity by the fact that a scalar quantity possesses only magnitude, whereas a vector quantity possesses both magnitude and direction
(1) In Fortran 90, a single object of any intrinsic or derived type A structure is scalar even if it has a component that is an array The rank of a scalar is 0 (2) A nonvectorized, single numerical value that represents one aspect of a physical quantity and may be represented on a scale as a point This term often refers to a floating-point or integer computation that is not vectorized; more generally, it also refers to logical and conditional (jump) computation
vector
scalar curl
The coefficient of k in the three-dimensional curl of a two-dimensional vector field

Since the curl of the vector field \vec{F}=(xy,xy,0) is the vector field \vec{\nabla}\times\vec{F}=(0,0,y-x), the scalar curl of the vector field \vec{G}=(xy,xy) is the scalar field y-x\;.

scalar field
A function that assigns a scalar value to every point in space
scalar function
Any function whose domain is a vector space and whose value is its scalar field
scalar multiplication
Multiplication of a vector by a scalar (which belongs to the vector space's field of scalars)
scalar product
The product of two vectors computed as the sum of the corresponding elements of the vectors, or, equivalently, as the product of the magnitudes of the vectors and the cosine of the angle between their directions
scalar products
plural form of scalar product
scalar architecture
design of a microprocessor with only one data pipeline
scalar field
a field of scalars
scalar matrix
a diagonal matrix in which all of the diagonal elements are equal
scalar product
The numerical product of the lengths of two vectors and the cosine of the angle between them. Also called dot product, inner product
scalar product
a real number (a scalar) that is the product of two vectors
