Size inputs, specified by a comma-separated list of integers. For example,false(2,3)returns a 2-by-3 array of logical zeros. If the size of any dimension is0, thenFis an empty array. If the size of any dimension is negative, then it is treated as0. ...
**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...

To access the current axes or chart without forcing the creation of Cartesian axes, use dot notation to query the figure CurrentAxes property. MATLAB® returns an empty array if there is no current axes. fig = gcf; ax = fig.CurrentAxes;Version...

Size of each dimension, specified as two or more integer values, defines X as a sz1-by...-by-szN array. If the size of any dimension is 0, then X is an empty array. If the size of any dimension is negative, then it is treated as 0. If any trailing dimensions greater than 2 ...
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(...
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...
