What's your question?

DGM 2023-12-8

Besides not actually saying what you want, you haven't included the working text.rtf. Are you aware that text.rtf is not a plain text file? I have to ask, because you're processing it like it's plain text when it's not. Disregarding array orientation errors, you're trying to fill your dictionary with a bunch of markup garbage that's not body text.

在 MATLAB Online 中打开

I fixed the improper concatenation and bad inputs to bar()

Program_Pr11('text.rtf.fakeextension.txt')

Of course, the bar labels are unreadable at this figure scale. I can't change that on the forum.

So what are those unique characters?

unique_chars =

'

$*-./0123456789;ABCDFHILNOQRSTWXYZ\_abcdefghijklmnopqrstuvwxy{}'

Let's look at the RTF file. Note that there aren't any uppercase characters or punctuation.

Let's see what the dictionary looks like:

words =
