Hey Everyone: I'm going to try and phrase this as best I can, I'm quite new to matlab and coding but I need help with this vital skill.

I want to write a for loop that checks multiple conditions:

This is my Matrix I will analyse. 
[170	284	60
292	380	69
294	397	82]

I want to check if element 1 is greater than some number, element 2 is greater than some number and element 3 is greater than some number. I also want it to check row by row and tell it to consider [170 284 60] as row 1, [292 380 69] as row 2 and [294 397 82] is row 3.

Can anyone help me out?

在 MATLAB Online 中打开

If you want to use a for loop, you could have a look at if statement with multiple conditions

% Your conditions
a = 200; 
b = 200;
c = 80;
A = [170 284 60; 292 380 69; 294 397 82];
for i = 1:3
   if A(i,1) > a && A(i,2) > b && A(i,3) > c
       disp(A(i,:))  % display rows that fulfill all conditions.
   end
end
