Exempel på hur man kan använda SCALAR i en mening

• The addition and multiplication operations together give A the structure of a ring; the addition and scalar multiplication operations together give A the structure of a module or vector space over K.
• If X is the base field F, then the map is called a bilinear form, which are well-studied (for example: scalar product, inner product, and quadratic form).
• In vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point.
• Moduli (physics), scalar fields for which the potential energy function has continuous families of global minima.
• In kinematics, the speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a non-negative scalar quantity.
• Multilinear subspace in multilinear algebra, a subset of a tensor space that is closed under addition and scalar multiplication.
• In simple cases, this function can be represented as a two-dimensional graph of an independent scalar input versus the dependent scalar output (known as a transfer curve or characteristic curve).
• UTF-8 is capable of encoding all 1,112,064 valid Unicode scalar values using a variable-width encoding of one to four one-byte (8-bit) code units.
• The operations of vector addition and scalar multiplication must satisfy certain requirements, called vector axioms.
• Examples of scalar fields in applications include the temperature distribution throughout space, the pressure distribution in a fluid, and spin-zero quantum fields (known as scalar bosons), such as the Higgs field.
• In physics, quintessence is a hypothetical form of dark energy, more precisely a scalar field, postulated as an explanation of the observation of an accelerating rate of expansion of the universe.
• In vector calculus flux is a scalar quantity, defined as the surface integral of the perpendicular component of a vector field over a surface.
• Random vectors can be subjected to the same kinds of algebraic operations as can non-random vectors: addition, subtraction, multiplication by a scalar, and the taking of inner products.
• In contrast to a scalar processor, which can execute at most one single instruction per clock cycle, a superscalar processor can execute more than one instruction during a clock cycle by simultaneously dispatching multiple instructions to different execution units on the processor.
• Lorentz scalar, a quantity in the theory of relativity which is invariant under a Lorentz transformation.
• A singularity in general relativity can be defined by the scalar invariant curvature becoming infinite or, better, by a geodesic being incomplete.
• From the definition of vector spaces, it follows that subspaces are nonempty, and are closed under sums and under scalar multiples.
• This is in contrast to scalar processors, whose instructions operate on single data items only, and in contrast to some of those same scalar processors having additional single instruction, multiple data (SIMD) or SIMD within a register (SWAR) Arithmetic Units.
• The irrotationality of a potential flow is due to the curl of the gradient of a scalar always being equal to zero.
• It was purely scalar and completed one instruction per cycle, so the performance was 20 MIPS or 20 megaflops for single precision and 10 MFLOPS for double.
