Originally trying to plot data from a table until I realized the data string format is incorrect i.e '10/08/2018 6:30:32 PM' Im assuming the function wont plot the character array hence I would need to convert the string to number format. I extracted the column from a table and conv...
= str2num(txt)converts a character array or string scalar to a numeric matrix. The input can include spaces, commas, and semicolons to indicate separate elements. Ifstr2numcannot parse the input as numeric values, then it returns an empty matrix. Thestr2numfunction does not convert cell arrays...

Convert String Arrays to Numeric Arrays You can convert text to numbers using the str2double function. Create a string that represents a number. Convert it to a numeric scalar. str = "81470.5" str = "81470.5" X = str2double(str) X = 8.1470e+04 Create a string array representing numbers...
CAUTION: STR2NUM uses EVAL to convert the input argument, so side effects can occur if the string contains calls to functions. Use 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...
