Include "a" character in a wordcloud

I am just trying to plot a simple wordcloud of grades which has a grade string, say,

grade='DBBBDBEFBFFASBCBABCCSBCAABBCBACDBFDBAFDAACAFAACABBFABCBAACF'

when I plot it using,

>>wordcloud(grade)

the function removes all Grade A information. How do I include the grade A in the plot?

As in Guillaume's answer, the key missing piece in the original post is the transpose. Given:

grade='DBBBDBEFBFFASBCBABCCSBCAABBCBACDBFDBAFDAACAFAACABBFABCBAACF';

The following does not work:

wordcloud(grade);

But the transpose does ("work" meaning create a word cloud, but with "A" removed):

wordcloud(grade');

Function takes column matrix. That's why!

Bear in mind that this is with base matlab. The text analytics toolbox, which I don't have, may have some better ways of doing what you want.

I'm simply converting your char array into a categorical array. It doesn't look like wordcloud does any filtering on categorical arrays:

grade='DBBBDBEFBFFASBCBABCCSBCAABBCBACDBFDBAFDAACAFAACABBFABCBAACF'
wordcloud(categorical(cellstr(grade')))

displays

This is what I was looking for. Thanks.
