Similarly, if a file has columns of data that store dates and times as text, you can read the data from those columns into datetime or duration arrays, making the data more useful for analysis. You can also use the char function to convert these values to character vectors. Also, some functions, such as the readcell , readvars , and readtable functions, read text from files and automatically convert text representing dates and times to datetime or duration arrays. To convert d to text, use the string function. Similarly, you can convert duration values. For example, first create a duration value that represents 3 hours and 30 minutes. One way to create this value is to use the hours and minutes functions. These functions create duration values that you can then combine. One common use of such strings is to add them to plot labels or file names.
