채택된 답변:chicken vector Hello, I have a vector of times for example [t1 t2 t3 t4]. I also have a vector of values A=[a1 a2 a3 ] .I need to plot between t1 and t2 the constant value a1, between t2 and t3 the value a2, between t4 and t3 the value a3. How can...
z-coordinates of the bases of arrows, specified as a scalar, a vector, or a matrix. If X and Y are vectors and Z is a matrix, then size(Z) must equal [length(Y) length(X)]. If X and Y are matrices, then X, Y, Z, U, V, and W must be the same size. U— x-component...
scalar | vector | matrix x-components of arrows, specified as a scalar, vector, or matrix. If X and Y are vectors, then size(U) and size(V) must equal [length(Y) length(X)]. If X and Y are matrices, then X, Y, U, and V must be the same size. V— y-components scalar ...
用matlab绘制三维向量场，可以使用quiver3函数来完成。如z = y^2 - x^2的三维向量场 x =-3:0.5:3;y =-3:0.5:3;[X,Y] = meshgrid(x, y);Z = Y.^2 - X.^2;[U,V,W] = surfnorm(Z);figure(1)quiver3(Z,U,V,W)view(-35,45)xlabel('x'),ylabel('y'),zlabel('z'...
在MATLAB中调用dfield,呈现 : 如果我们要绘制常微分方程x′=x2−tx′=x2−t对应的矢量场图,我们可以输入对应的公式与参数值。在这里,上图中默认的常微分方程对应矢量场图: 在MATLAB中调用pplane,呈现 以默认的微分方程为例,可以绘制矢量场图:

boxplot(x) creates a box plot of the data in x. If x is a vector, boxplot plots one box. If x is a matrix, boxplot plots one box for each column of x. On each box, the central mark indicates the median, and the bottom and top edges of the box indicate the 25th and 75th...
with MATLAB 6.5 and earlier.LINE Create line.LINE(X,Y) adds the line in vectors X and Y to the current axes.If X and Y are matrices the same size, one line per column is added.LINE(X,Y,Z) creates lines in 3-D coordinates.LINE returns a column vector of handles ...
S-by-1bias vector and returns a handle to a plotted classification line. plotpc(W,B,H)takes an additional input, H Handle to last plotted line and deletes the last line before plotting the new one. This function does not change the current axis and is intended to be called afterplotpv...
