I have a <20x1> cell array and each of them stores some data in the form of a string (as it appears to me!!!). I want to access each element of the cell as an individual string and split is in words.
The cell array I have is <20x1> cell array and to access each element as a cell I am using a for loop.
for i=1:20
line=newline{i}
end
It shows me a all the elements within the array. Now since line is a string, I apply strsplit function to retrieve the words in the string.
for i=1:20
words(i,:)=strsplit(line)
end
This gives me an error message :
??? Undefined function or method 'strsplit' for input
arguments of type 'char'.
Error in ==> chk at 15
words=strsplit(newline{i})
can anyone explain me where I am wrong? Any help will be appreciated. Thanks in advance.
My guess is that you're using a version
of Matlab prior to R2013a. Despite the fact that they are generic functions and should have bee added ages ago, strsplit
and strjoin
were only added in this most recent version.
There are several ways you can get around not having access to strsplit
if all you want to do is split a string into words. If all of your whitespaces are simple spaces you can just use strread
like this:
strread(line,'%s','delimiter',' ')
However, textscan
should be more robust:
textscan(line,'%s')
Using regexp
should also be robust, but will likely be slower:
regexp(line,'\s+','split')
All of these return outputs as cell arrays of strings (your words), just like strsplit
. The output from textscan
is transposed relative to the others.
