Hello guys,
I am encoutering a probem with a script I am currently working on. The idea is that any row of a column named "Anxiety_RESP" that does not contain a value ([ ]) should be replaced with the corresponding value found in a column named "blackscreen_RESP".
So far, I wrote the following code:
for k=1:height(data_pp)
if data_pp.Anxiety_RESP == [];
data_pp.Anxiety_RESP = data_pp.blackscreen_RESP;
else data_pp.Anxiety_RESP = data_pp.Anxiety_RESP;
end
However, the code does not work and the following error is displayed:
Error using ==
Matrix dimensions must agree.
Error in CorrectScript (line 41)
if data_pp.Anxiety_RESP == [];
Thank you in advance!
Best wishes,
Luisa

Well, you do have to use it correctly. I suggest looking at the documentation page I linked to.
if isempty(data_pp.Anxiety_RESP)
We don't know what Ansiety_RESP is. You may need to do this.
for k=1:height(data_pp)
if isempty(data_pp.Anxiety_RESP(k))
