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...
In Matlab, str2num and str2double function is used for a string to number conversion. The function is used to convert text or string to a numeric value called as str2num function. The str2num function supports one or more numbers separated by spaces, decimal point, and commas. The input strin...

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...
Space characters, or the lack of them, can be significant. For instance,str2num('1+2i')andstr2num('1 + 2i')both return the complex number1.0000 + 2.0000i, whilestr2num('1 +2i')returns the 1-by-2 vector[1.0000 + 0.0000i 0.0000 + 2.0000i]. To avoid this problem, use thestr2double...
Create a string array in which each element represents a number. To convert the string array to a numeric array, use the double function. Get str = ["256","3.1416","8.9e-3"] str = 1x3 string "256" "3.1416" "8.9e-3" Get X = double(str) X = 1×3 256.0000 3.1416 0.0089 ...
