MATLAB Online で開く This is not pretty, but you can split the string on the ':' and compute the number of seconds since midnight. The code below used cellfun to vectorize the code; a for loop could be use and might be easier to understand (but likely sacrificing performance). ...
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...
