MATLAB: How to write an If() AND() function in MATLAB

if statementMATLAB

Hi,
I was wondering what the best way to write an IF() AND() function is. For example if I have the following information, I want to select the values in row 3 associated with the values that have 11 in column1 and have a 1 in column2. How do I write the code to do this?
column1  column2  column 3  column 4
11          1        6        5
11          1        8        2
12          1        7        0
21          1        3        8
21          1        2        9

Best Answer

This works:
M = [11          1        6        5
    11          1        8        2
    12          1        7        0
    21          1        3        8
    21          1        2        9];
Out = M((M(:,1) == 11) & (M(:,2) == 1),3)
Out =
     6
     8
