matlab数组操作 1且其他位置元素为0的n × n 单位矩阵。 zeros(n1,n2):零矩阵 ones(n1,n2):元素全为1的矩阵 diag(): 对角矩阵 mean():中位数 size():多少行,多少列 length():返回X中最大数组维度的长度find():查找非零元素的索引和值 智能推荐 ...
Use the logicalnotoperator onXto locate the zeros. AI检测代码解析 k2 = find(~X) 1. AI检测代码解析 k2 =4×12 3 4 6 1. 2. 3. 4. 5. 6. k= find(X,n)返回与 x 中的非零元素对应的前 n 个索引。 例子: Elements Satisfying a Condition Find the first five elements that are less ...
在MATLAB中,可以使用find()函数来查找小数。find()函数用于查找数组中满足特定条件的元素的索引。 要在MATLAB中使用find()函数查找小数,可以按照以下步骤进行操作: 1. 创...
This workflow creates a variable in the base workspace representing a GPZ Matrix. The steps are: Launch the app with the MATLAB command ctlefitter. Import a CTLE frequency response. Adjust preprocess options for your transfer function data. Configure parameters of the rational function from RF...
I would like to find the indices of the zero elements in the following subsection of the matrix 테마복사 Tarr(5:5:end,2:end) An then replace those with some numbers I desire. I know this must be fairly easy, however I cant seem to be able to find a straightforward way. KR...
%Find attribute numbers in the dataset attributesNum = size(matrix,2) - 1 ; %create an empty matrix for inputs X = zeros(attributesNum,1); %İt is a for loop for take inputs from user fori=1:attributesNum values = input('Enter Value: '); ...
X=zeros(4,2,3);X([1121921])=1 X=X(:,:,1)=10000000X(:,:,2)=00000010X(:,:,3)=01001000 [row,col]=find(X) row=4×11431 col=4×11356 最后介绍下线性索引: 线性索引允许使用单个下标索引到数组中, 如 a (k)。MATLAB®将数组视为单个列向量, 并将每个列附加到上一列的底部。因此, 线...
% pad the array with zeros so we don't have % to check the edges conditionally every time inpict = padarray(inpict,[1 1],padval,'both'); outpict = zeros(sz); forrow = 2:sz(1)+1 forcol = 2:sz(2)+1 yy = row-1:row+1; ...
Find number of zeros in a part of a matrixI need to find the number of zeros that are contained in a part of a matrix. For example if the matrix is [1 2 2 2 2 2 0 2 2 2 0 3 0 0 4 5 6 7 0 0 8] is there a fast way to get the number of zeros between the fifth ...
