Coding bug - IF statement

I am working on a code right now where I need to compare a particular column of a matrix using IF statement. For some reason it wasn't working so I tried something simpler -
------
a=[1;0;0]
b=[0;0;1]
if a~=b
disp("hfsdfsdkhl")
end
-----
I am relatively new on MATLAB and dont get why the IF statement doesnot satisfy. This would not work either. Can someone help, please.

Comparing arrays like this does not work properly with the if-else block. See the output of your comparison
>> a=[1;0;0]
b=[0;0;1]
a =
1
0
0
b =
0
0
1
>> a~=b
ans =
3×1 logical array
1
0
1
It is a 3 element vector. You can use isequal() to see if all elements are equal or not
a=[1;0;0];
b=[0;0;1];
if ~isequal(a,b)
disp("hfsdfsdkhl")
end
You can also use
any(a~=b)
% or
all(a==b)
