I have 2 tables, with 1 column and 24 rows each.
I want to find the diferrence between each value in every row.
for example
T1=[1.5
2.5
3.5
4.5]
T2=[1.2
2
3
4]
The answer must be
Diff=[ 0.3
0.5
0.5
0.5]

y = T1 - T2

I move the tables in other script, and the diffence now is correct. Maybe there is a missunderstanding in the code!
Thank yo for your help!

Ran in:
T1=[1.5
2.5
3.5
4.5];
T2=[1.2
2
3
4];
Difference = T1 - T2
Difference = 4×1
0.3000 0.5000 0.5000 0.5000

i already did this but the answer is different. I will upload my code to see it.
