I wanted to know how to go about reshaping a character array horizontally, starting from the first index in the first row, and then the second and so on. So I want to change:

text =
  3×5 char array
    'words'
    'words'
    'words'

Into

text =
1x15 char array
'wordswordswords'

How do I do this?

Using the reshape function:

text1 = ['words'; 'words'; 'words']
text2 = reshape(text1', 1, [])

producing:

text1 =
  3×5 char array
    'words'
    'words'
    'words'
text2 =
    'wordswordswords'

I know it's not the class used in que question, but it's just to share how to do it with strings.

In case a string array is used instead of a char array, this can be done with the function strjoin:

text_1 = ["words" ; "words" ; "words"]
text_1 = 3x1 string array
    "words"
    "words"
    "words"
text_2 = strjoin(text_1, "")
text_2 = "wordswordswords"
