If the'rows'flag is not specified, thenCis a column vector unless bothAandBare row vectors, in which caseCis a row vector. For example,setxor([],[1 2])returns a column vector. If the'rows'flag is specified, thenCis a matrix containing the rows ofAandBthat are not in the intersecti...
When finding the gradient of a scalar functionfwith respect to a row or column vectorv,gradientuses the convention of always returning the output as a column vector. For example, iffis a 1-by-1 scalar andvis a 1-by-3 row vector, thengradient(f,v)finds the derivative offwith respect ...
y-coordinates of Voronoi edges, returned as a column vector. Graphics array, returned as an array of two line object handles representing the points and edges of the diagram. More About collapse all Given a point in a set of coplanar points, you can draw a boundary around it that includes...
Finally, pass these anonymous functions to % FMINCON: % % a1 = 2; a2 = 1.5; % define parameters first % options = optimoptions('fmincon','Algorithm','interior-point'); % run interior-point algorithm % x = fmincon(@(x) myfun(x,a1),[1;2],[],[],[],[],[],[],@(x) mycon(...
3-D arraysuandvrepresent the velocity of the air current in 3-D vector fields. Use the fifth page of the arrays. Define the starting position of four hypothetical particles. In this case, the four starting locations are (80, 20), (80, 30), (80, 40), and (80, 50). ...
Create a column vector of categorical data specifying gender. Get gender = categorical({'Male';'Female';'Female';'Male';'Female'}); Create dummy variables for gender. Get dv = dummyvar(gender) dv = 5×2 0 1 1 0 1 0 0 1 1 0 dv has five rows corresponding to the number of...
error('Contingency: Requires two vector arguments') return end Cont=zeros(max(Mem1),max(Mem2)); for i = 1:length(Mem1) Cont(Mem1(i),Mem2(i))=Cont(Mem1(i),Mem2(i))+1; end程序中包含了四种聚类度量方法:Adjusted Rand index、Rand index、Mirkin index、Hubert index。结果...
The sprintf function formats the values in A1,...,An in column order. If formatSpec is a string, then so is the output str. Otherwise, str is a character vector. To return multiple pieces of formatted text as a string array or a cell array of character vectors, use the compose ...
Acolormapis a matrix of values that define the colors for graphics objects such as surface, image, and patch objects. MATLAB®draws the objects by mapping data values to colors in the colormap. Colormaps can be any length, but must be three columns wide. Each row in the matrix defines...
Defining the matrix B ∈ NP ×NE such that its ith column is the vector Bi ∈ NP , we obtain the matrix equation G = B, where ∈ NP ×NE is the matrix representation of the Ritz projector E, taking a vector of coefficients of a function expressed in terms of the basis of VhE to...
