emptyStrArray = string.empty;这将创建一个空的字符串数组emptyStrArray。在MATLAB中，字符串数组是一种特殊类型的数组，其中每个元素都是一个字符串。空字符串数组在某些情况下很有用，例如在需要动态添加元素的情况下，可以先创建一个空的字符串数组，然后逐步添加元素。另外，可以使用函数zeros、ones或者empty来...
Create a string vector whose elements are strings with no characters.str1is nonempty since none of its dimensions have length zero. str1 = strings(1,3) str1 =1x3 string"" "" "" TF1 = isempty(str1) TF1 =logical0 Create a 0-by-3 string array and test if it is empty. ...
Unable to perform assignment because value of type 'string' is not convertible to 'uint8'. Note Because empty arrays must have at least one dimension of size 0, you cannot useemptyto create a 3-by-3 array, for example. MATLAB does not have a null value, so all nonempty arrays must ...

inputname(argnum) returns the workspace variable name corresponding to the argument number argnum. If the input argument has no name (for example, if it is an expression instead of a variable), the inputname command returns the empty string (”)...
