The term "gradient" has several meanings in mathematics. The simplest is as a synonym for slope. The more general gradient, called simply "the" gradient in vector analysis, is a vector operator denoted and som
the graph of alinear function 是一条直线line,这条直线的函数表达式也称作直线方程Equations of a straight line,斜截式gradient-intercept form是y=ka+b,其中常数k称为这条直线的斜率gradient,b称为这条直线的y截距y-intercept。我们需要知道的是:
GRADIENT_TRIANGLE 结构指定 GradientFill 函数中 pVertex 数组中三个顶点的索引。 这三个顶点构成一个三角形。

where is the ideal captured images (all the captured I under different angular illumination in vector form), is the corresponding linear transform matrix incorporating the Fourier transform and the low-pass filtering and is the sample’s HR spectrum (Φ in vector form). This is a standard phase...
A simple choice for a direction of search to find a minimum is to take d(k) as the negative gradient vector at the point x(k). For a sufficiently small step value this can be shown to guarantee a reduction in the function value. This leads to an algorithm of the form (1.5)x(k+...

where clearly the modifed function $f_h$ depends on stepsize $h$, such that $f_h$ is in the form of f_h(x):= f(x) + f_1(x)h + f_2(x)h^2+\cdots, where $f_i$ are the correct terms that will be determined later, and \hat{\theta} denote the solution of the mo...

The surface tension was measured for liquid tungsten barely above the melting point and in the under-cooled phase, 3360 < T(K) < 3700. The temperature interval of 350 K can be considered as adequate for the determination of the temperature coefficient. A linear fit of the form ...
