Keep selected rows in a struct file

Question

0 个投票

Hello,

I have a 600x1 struct file with 5 fields. One of the field is 'labels', containing random numbers from 1 to 1000. and a separate array (jn) 1x 500 containg 500 integers.

I am trying to remove the rows in the struct file with 'labels' which do not match the integers in the 'labels' array.

The solutions already on internet does not seem to work for me.

Thanks

I tried the following, where S is the struct and jn is the array

jn=num2cell(jn);
idx = ismember({S.labels}', jn);
Sx = S(idx);

The following error appears

Error using cell/ismember (line 34)
Input A of class cell and input B of class char must be cell arrays of character vectors, unless one is a character vector.

%%jn is the array, (not converted to cell array that I was originally
%%converting it to , and I should have used square brackets instead of curly brackets)
idx = ismember([S.loc_id]', jn);
Sx = S(idx);
