gradientcalculates values along the edges of the matrix withsingle-sided differences: G(:,1) = A(:,2) - A(:,1); G(:,N) = A(:,N) - A(:,N-1); If you specify the point spacing, thengradientscales the differences appropriately. If you specify two or more outputs, then the fun...
[FX,FY] = gradient(F) returns the x and y components of the two-dimensional numerical gradient of matrix F. The additional output FY corresponds to ∂F/∂y, which are the differences in the y (vertical) direction. The spacing between points in each direction is assumed to be 1. exa...

It is most often applied to a real function of three variables , and may be denoted (1) For general curvilinear coordinates, the gradient is given by (2) which simplifies to (3) in Cartesian coordinates. The direction of is the orientation in which the directional derivative has...
2 Jacobian matrix 雅可比矩阵的重要性在于它体现了一个可微方程与给出点的最优线性逼近。 因此,雅可比矩阵类似于多元函数的导数。 The Jacobian of a vector-valued function in several variables generalizes the gradient of a scalar-valued function in several variables, which in turn generalizes the derivative...

The function Φ(a0, a1, a2) in (1.21) is the weighted quadratic error between the image I(x, y) and the linear fit I˜xy in a 3 × 3 neighborhood centered at (x0, y0). The weights w(x –x0, y –y0) take into account the different Euclidean distances of horizontal, ...
Because H(Ma) is a monotonously decreasing function, there is a one-to-one correlation between the final film thickness and the mean surface tension gradient τ¯. This means that if one has a measurement of the final film thickness, one can use the model to calculate the mean surface ...
