STR2DOUBLE to avoid such side effects or when S contains a single number. str2num的功能是将字符串矩阵转换成数值数组,字符串必须是ASCII码表中的可转化成数值的字符,如果字符串数组不是一个有效的数字或者不能过程一个矩阵,str2num函数就会返回一个空的矩阵,[X,OK]=STR2NUM(S),如果转换失败OK=0. 注意:str2...
num2str 文档中有一些我不完全理解的提示。 [cc lang="matlab"]Note: If you specify precision to exceed the precision of the input floating-point data type, the results might not match the input values to the precision you specified. The result depends on your computer hardware and operating syst...

You can represent text in MATLAB® using string arrays where each element of a string array stores a sequence of characters. The sequences can have different lengths without padding, such as "yes" and "no". A string array that has only one element is also called a string scalar. You ...
