I have a data of
linedata = [1 1 2 2
2 2 3 1.5
3 3 4 2.2
4 4 5 6.8
5 4 6 1
6 5 7 5.1
7 6 8 2.5
8 7 9 3.3
9 8 10 2.8
10 8 11 1.4
11 10 12 3.2
12 11 13 2.7
13 12 14 1.9
14 13 15 4.5];
I would like to ask how can i check for value 7 and 8 in column 2 and column 3. I am using find function to find the value but it cant seems to work. Can anyone help? Thanks in advance.

It is unclear to me exactly what you want. Do you want to check the two columns separately? Or are you trying to check the condition in both columns?
For example, are you trying to check if column 2 is equal to 7, while column 3 is equal to 8?
Do you need the indices, or is logical output ok?
Can you tell us what exactly you expect the output to be for this input? (Better to express it in MATLAB syntax, not English words.)

Explain exactly what "check for" means. Until then, try
% See if row 7 and 8, both in column 2, match
if linedata(7, 2) == linedata(8, 2)
fprintf(['linedata(7, 2) equals linedata(8, 2)\n');
else
fprintf(['linedata(7, 2) does not equal linedata(8, 2)\n');
end
% See if row 7 and 8, both in column 2, match
if linedata(7, 3) == linedata(8, 3)
fprintf(['linedata(7, 3) equals linedata(8, 3)\n');
else
fprintf(['linedata(7, 3) does not equal linedata(8, 3)\n');
end
