3、点选"Edit Text Update Function"，出现一个m文件编辑器。内容如下： function output_txt = myfunction(obj,event_obj) % Display the position of the data cursor % obj Currently not used (empty) % event_obj Handle to event object output_txt Data cursor text string (stri...
expand an empty array into a nonempty array by assigning a specific value into the empty array. Any object you assign to the array must be of the same class or convertible to the class of the empty array. For example, create an empty array ofuint8and try to assign a string value to ...

Hi, I'm using a structure to hold some text data. The fields of the structure are initialised as cells. However it seems that if the field is left empty then the value is converted to a double meaning I can't consistently index that value. Do I need to specifically test each value ...
power of 10 scale factor, and an 'i' or 'j' for a complex unit. If the string S does not represent a valid number or matrix, STR2NUM(S) returns the empty matrix. [X,OK]=STR2NUM(S) will return OK=0 if the conversion failed. ...
在MATLAB中,可以使用isempty函数来判断单元格数组中的元素是否为空数组。isempty函数返回一个逻辑值,如果元素为空数组,则返回true,否则返回false。 以下是一个示例代码,演示如何在MATLAB中找到单元格数组中的空数组: 代码语言:matlab 复制 % 创建一个包含空数组的单元格数组 cellArray = {[], [1, 2, 3...
