A = ClassName.empty A = ClassName.empty(sz1,...,szN) A = ClassName.empty(sizeVector) Description Theemptymethod creates empty arrays of a given class. For an introduction to empty arrays in MATLAB®, seeEmpty Arrays. To test if an existing array is an empty array, useisempty. ...
**在条件语句中使用**: ```matlab if isempty(A) disp('Array A is empty.'); else disp('Array A is not empty.'); end ``` ### 注意事项 - 当检查多维数组时,即使某些维度的大小为 0,只要整个数组有一个或多个维度的大小不为 0,该数组就不被认为是空的。例如,`A = zeros(0, 5)` 是...
Determine whether array is empty collapse all in page Syntax TF = isempty(A) Description TF = isempty(A)returns logical1(true) ifAis empty, and logical0(false) otherwise. An empty array, table, or timetable has at least one dimension with length 0, such as 0-by-0 or 0-by-5. ...
IfAis an empty 0-by-0 matrix,prod(A)returns1. IfAis a multidimensional array, thenprod(A)acts along thefirst nonsingleton dimensionand returns an array of products. The size ofBin this dimension reduces to1, while the sizes of all other dimensions remain the same as inA. ...
If the size of any dimension is0, thenXis an empty array. If the size of any dimension is negative, then it is treated as0. Beyond the second dimension,zerosignores trailing dimensions with a size of1. For example,zeros([3 1 1 1])produces a 3-by-1 vector of zeros. ...
To get the handle of the current figure without forcing the creation of a figure if one does not exist, query theCurrentFigureproperty on the root object. fig = get(groot,'CurrentFigure'); MATLAB®returnsfigas an empty array if there is no current figure. ...
row = fgetl(fid); if isempty(row) break; end array{i} = str2num...

Determine if any array elements are nonzero(确定是否有任何数组元素非零) Syntax B = any(A) B = any(A,dim) Description B = any(A) 沿着A的第一个数组维度进行测试,其大小不等于1,并确定是否有任何元素是非零数字或逻辑1(...
