i am trying to filter a dataset by using ismember(...), which gives me a logical array and the indexes. now i want to put it in a table but i'm not sure how to do that. can someone help me out?
code:
[a,b]=ismember('meta_data_mri.MRID','MRIdata.subjects');
tbl_meta_data_mri_filtered = ???
output:
>> [a,b]=ismember('meta_data_mri.MRID','MRIdata.subjects')
a =
1×18 logical array
0 1 1 1 0 1 1 1 1 0 0 0 0 1 1 1 1 0
b =
Columns 1 through 12
0 13 6 5 0 4 5 6 5 0 0 0
Columns 13 through 18
0 8 1 2 3 0

That's doing ismember with the names of the files.
[a,b]=ismember('meta_data_mri.MRID','MRIdata.subjects')
[a,b]=ismember('abbacadcemoqsuwy','abcdefghijkrstuvwxyz')
If you want to operate on the actual data, first you must read the contents of the files into variables, e.g., using readtable, readmatrix, or readcell, etc., depending on the format and contents of the files.
