MATLAB: How to write this below IF condition in MATLAB

Let I have dataset with 4 variable = c1, c2, c3, c4 from 3 observations. I want to make a conclusion in this 3 observation based on the "IF" condition (I wrote this IF condition in excel):
=IF(AND(C1>C2,C1>C3,C1>C4),1,IF(AND(C2>C1,C2>C3,C2>C4),2,IF(AND(C3>C1,C3>C2,C3>C4),3,4)))
    c1      c2      c3        c4       conclusion
  0.05000 0.77426  0.07760  0.39404       ?
  0.99888 0.32245  0.00001  0.00003       ?
  0.99999 0.00000  0.00110  0.00000       ?
Note: in matlab there is no c1,c2,c3,c4 but column: 1,2,3,4
Can some one help me, how to write the code of this problem in matlab? many thanks!

So what exactly do you have? I don't know if you have an array or a table. To get c1,c2,c3, and c4 from a table you do
c1 = t.c1;
c2 = t.c2;
c3 = t.c3;
c4 = t.c4;
To get c1,c2,c3, and c4 from an array you do
c1 = c(:, 1);
c2 = c(:, 2);
c3 = c(:, 3);
c4 = c(:, 4);
Then to do
IF(AND(C1>C2,C1>C3,C1>C4),1,IF(AND(C2>C1,C2>C3,C2>C4),2,IF(AND(C3>C1,C3>C2,C3>C4),3,4)))
you need to specify whether you want that done on a row by row basis , or if all elements (all rows) in something like C1>C2 need to be true. Which is it?
