Problem 43674. String Array Basics, Part 3: Convert Cell Array with Missing Values to String Array

Created by Peng Liu in Community

String array and cell array are two types of containers for storing pieces of data. In this problem, you will be given a cell array of character vectors. Your job is to convert the cell array to a string array, which stores the same pieces of text data.

The Part 1 assuming no missing values in the input cell array is a good starting point. In this problem, the missing values for cell array of character vectors, denoted {''} (i.e., cell of empty character), need to be converted to the missing values for string arrays, denoted < missing >.

Refer to the R2016b documentation for more information on the missing values for different data types.


>> x = {'I', '', '', 'MATLAB'}
x =
  1×4 cell array
    'I'    ''    ''    'MATLAB'
>> y = string('I'); y(4) = 'MATLAB'
y = 
  1×4 string array
    "I"    <missing>    <missing>    "MATLAB"
