How to reshape an array horizontally
显示 更早的评论
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?

text1 = ['words'; 'words'; 'words']
text2 = reshape(text1', 1, [])
producing:
text1 =
3×5 char array
'words'
'words'
'words'
text2 =
'wordswordswords'
.

@Brett: The key is to transpose the array first so that the letters line up in memory the way you want them to before doing the reshape (which preserves ordering in memory). Since MATLAB array memory is column ordered, that means lining the letters up in columns first.

Brett Baxter — My pleasure!
‘so then if I want to do operations down rows instead of columns, I have to transpose first’
That depends on what you want to do. Here, yes.

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_2 = strjoin(text_1, "")
