Clc;
Clear all;
r1=randperm(2,1);
r2=randperm(2,1);
a=sort(r1);
b=sort(r2);
x=[a,b]
q=[2,1]
If x~=q
Disp(X). %cannot get it to correctly display the numbers of the variable every time it doesn't equal q
Else
Disp('x is equal to q')
End

why do you sort a scalar anyway?
r1 and r2 are coin tosses, they are either 'head' or 'tail'
and instead of
r1=randperm(2,1);
r2=randperm(2,1);
why not just
x=randperm(2,2);

Using two separate randperm is selection with replacement. Using one randperm would be selection without replacement.
For selection with replacement you could use randi()

Don't use uppercase for Matlab function, It's not Clc but clc and not If but if
clc;
clear
r1=randperm(2,1);
r2=randperm(2,1);
A=sort(r1);
B=sort(r2);
X=[A,B]
q=[2,1]
if X~=q
disp(X) %cannot get it to correctly display the numbers of the variable every time it doesn't equal q
else
Disp('x is equal to q')
end

Still fails, I have what you say always works now every time it says x is equal to q when that is not true if r2 is equal to 2 than x would be 2,2 so not equal to q

clc;
r1=randperm(2,1)
r2=randperm(2,1)
X=[r1,r2];
q=[2,1];
if ~isequal(X,q)
disp(X) %cannot get it to correctly display the numbers of the variable every time it doesn't equal q
else
disp('x is equal to q')
end
