The phrase "a linear operation" is correct and usable in written English.
It can be used in mathematical or scientific contexts to describe an operation that satisfies the properties of additivity and homogeneity.
Example: "In linear algebra, a linear operation can be represented by a matrix multiplication."
Alternatives: "a linear transformation" or "a linear function".
Eigenvalue, one of a set of discrete values of a parameter, k, in an equation of the form Pψ = kψ, in which P is a linear operator (that is, a symbol denoting a linear operation to be performed), for which there are solutions satisfying given boundary conditions.
And squaring it is definitely not a linear operation.
We'll be wrong, but not by much; addition, as a linear operation, is pretty forgiving.
While not normally though of in such terms, the fact that an impulse function in space transforms to a complex exponential (in spatial frequency) completely describes the Fourier transform as a linear operation.
We experimentally observe on some devices a compensation of hardening effects, allowing a linear operation of torsion angle up to 13°.
The steam flow should nonetheless be proportional to the final desired quantity, output power, of the turbine to obtain a linear operation.
The precoding strategy at the BS includes an encoding operation and a subsequent linear operation with a filter matrix.
In the absence of noise, deconvolution is a simple linear operation that yields the exact fluorophore distribution in a single step.
There are a few side quests but for the most part it's a pretty linear operation.
It was established in [24] that in single-input single-output (SISO) OFDM a time-domain (TD) equivalent to LS estimate could be obtained using a simple linear operation on the received signal, if the used pilot sequence fulfills certain conditions.
The SbFE revealed a good linear operation in the examined concentration range of 2.5 80 μg L−1 Hg II) with R2 of 0.998, an estimated limit of detection (3σ) of 0.39 μg L−1 obtained after a 300 s accumulation step, and a favourable reproducibility with RSD of 2.3% (30 μg L−1, n = 10).
