**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
Create a 0-by-3 string array and test if it is empty. str2 = strings(0,3); TF2 = isempty(str2) TF2 =logical1 Input Arguments collapse all Input array or table, specified as a scalar, vector, matrix, multidimensional array, table, or timetable. ...

If you specify more thanndims(A)output arguments, then the extra trailing arguments are returned as1. Data Types:double Tips To determine if an array is empty, a scalar, or a matrix, use the functionsisempty,isscalar, andismatrix. You can also determine the orientation of a vector with ...
If size(A) and size(B) are the same, concatenate the arrays; otherwise, display a warning and return an empty array. Get if isequal(size(A),size(B)) C = [A; B]; else disp('A and B are not the same size.') C = []; end A and B are not the same size. Compare...
If A is an empty 0-by-0 matrix, any(A) returns logical 0 (false). If A is a multidimensional array, any(A) acts along the first array dimension whose size does not equal 1 and returns an array of logical values. The size of this dimension becomes 1, while the sizes of all other...
