According to the theory of scalar diffraction, first, the equipollence of spatial distribution of the plane-wave interferential field and parallel projective sine grating is discussed.
It's a little awkward to work with at 1st, because that left hand side represents matrix factor multiplication, but the right hand side here is scalar vector multiplication.
Our concept of the character is actually a composition of multiple Unicode scalar values, and decomposing these correctly is critical to getting that fidelity with Unicode, the characters, and the string API.
我们对于字符概念实际上是由多个统一码标量值构成,正确地把它解构对于统一码精确性以及字符和字符串 API 精确性都至关重要。
You'll see in the following videos what I mean when I say that linear algebra topics tend to revolve around these two fundamental operations vector edition and scalar multiplication.
But some special vectors do remain on their own span, meaning the effect that the matrix has on such a vector is just to stretch it or squish it like a scalar.
Well, the span of two vectors is basically a way of asking, what are all the possible vectors you can reach using only these two fundamental operations, vector edition and scalar multiplication?
