I have imported some information from Excel, that's both strings and numbers. I read the Excel-file in MATLAB in raw format
Now, I have a column in a big matrix as
[1]
'1A'
[2]
[3]
[4]
[505]
[601]
[7]
[8]
this is how the xlsread command gave it to me. I want to convert all these into strings like ['1' , '1A', '2' and so on..] .
I am struggling to do it. I want no blank spaces in each element. I mean it should not be like [ ' 1', ' 1A', ' 2' and so on]....
Try to combine cellfun and num2str like this:
A = {1, '1A', 2, 3, 4, 505, 601, 7, 8}'
str = cellfun(@(c) num2str(c), A, 'UniformOutput', false).'
str =
'1' '1A' '2' '3' '4' '505' '601' '7' '8'
You can use num2str on stings, so you do not have to check if variable is a string or a numeric value. Note that the spaces in the result are between the elements, and not in the elements itself. So,
str(1)
ans =
'1'
str(2)
ans =
'1A'
If your input data may contain spaces (your sample didn't), you can eliminate those by using an additional cellfun like this:
cellfun(@(c) c(c~=' '), str, 'UniformOutput', false)
Side note: In most MATLAB functions, you can shorten parameter names, such as UniformOutput, false. This can be un, 0, uni, 0 ... etc, as long as the letters represent a unique parameter and can't mean something else. This is a nice trick if you write it in the command window, but I would avoid it in real code, as it could possibly break the code if The MathWorks determines to create a parameter called unit, UniformInput or something else starting with uni. Just a little tip =)
