I am trying to compare two string columns (of different dimensions) and I have typed in a code for that which is not working to my expectation. Any help would be highly appreciated!
So I have two string columns A (nx1) and B (mx1). After declaring these columns in my code,the conditions go like this:
for g = 1:length(A)
for h = 1:length(B)
if A(g) == B(h)
disp("%s %s\n",A(g),B(h));
end
end
end
When I ran this code, I got no matches. However, I know that there is at least 1 match (as I have seen the same strings in both the columns). So, any useful suggestions would be very helpful. Thank you in advance for your help!

When you say "string", do you mean character vectors and cell array of character vectors, or do you mean the R2016b and later string object ?

I have only a vague idea of what you are doing. My guess is that you re comparing individual elements of both strings.
This is likely easier with the ismember function. Depending on the result you want, you can combine this with the any function if you want a single logical result at the end.

Please help I'm trying to use string comparison to compare elements of the 2 strings and actually store the common in a variable, how do i go about it?

C = intersect(A, B)
A and B can be string arrays or cell arrays of character vectors.
