Hello,
I am new to Matlab with very little experience!
I have a variable set with 5 columns, and I am trying to get a data from one column based on the condition of other column..
For example, I like to get the corresponding value in column 5 based on column 3.
while i = 50 in column 3 find the value of 22 from column 5? By changing i, get the corresponding number from column 5?
1400 1 1 3 11
1500 2 50 5 22
1600 3 100 7 33
1700 4 200 9 44
…..
Thanks so much!
Regards’
Loran

Try this:
m=[...
1400 1 1 3 11;
1500 2 50 5 22;
1600 3 100 7 33;
1700 4 200 9 44]
col3equals50 = m(:,3)==50 % Logical vector of where column 3 value = 50
extractedCol5Numbers = m(col3equals50, 5)
In the command window:
m =
1400 1 1 3 11
1500 2 50 5 22
1600 3 100 7 33
1700 4 200 9 44
col3equals50 =
0
1
0
0
extractedCol5Numbers =
22
