拟合后matlab一直显示Complex value computed by model function, fitting cannot continue. Try using or tightening upper and lower bounds on coefficients. 更改了ua和us的初始变量,也没有效果。 注:程序中的数据为五幅图片,分别是fx在0.04、0.05、0.06、0.07、0.08/mm下的,拟合思路为用5幅图的同一位置(x,y...
The mean value theorem from complex analysis says that the value of an analytic function at a point equals the continuous average of the values over a circle centered at that point. If we approximate this average by taking the average of 16 values in a circle of radius 1 around our point,...

Notice that, by using this logistic function, the value of the attention coefficients is constrained to the open interval (0, 1), where aij = 0 implies that the feature ξj does not change the value of νi, and aij = 1 implies that it maximally changes the value of νi....
Complex networks have been used widely to model a large number of relationships. The outbreak of COVID-19 has had a huge impact on various complex networks
Each of these cells has been assigned an estimated population value. Out of the possible resolutions, we have opted for cells of 15 × 15 minutes of arc to constitute the basis of our model. This corresponds to an area of each cell approximately equivalent to an area of 25 × 25 km 2...
the multi-agent learning problems [6,7,8], but the optimal joint value function solution becomes complex as the number of agents increases. In human societies, when dealing with complex tasks or problems, people tend to decompose them into different levels of subtasks, and individuals take on...
A simplified model of the Leslie–Ericksen theory is used to solve the flow of liquid crystalline polymers, seen as viscous anisotropic fluids, making the assumptions of high viscosities and neglecting the director elasticity in the viscosity terms. The resulting equations, known as Ericksen's ''Tr...
This value can be lowered by optimizing the phase shifter efficiency, i.e. by using trenches, or by implementing other schemes to control the phase, such as the plasma dispersion effect. The off-the-chip activation function, required to get to the output as in Eq. (3), can be easily ...
value is guaranteed whenXis deterministic and there is only one initial condition (see Supplementary NoteIII). HavingI(X; G) = 0 implies thatU(X ∣ G) = U(G ∣ X) = 0, which again means thatGandXare independent. Any value in-between ofU(X ∣ G) ...
