# I need this program to only output one time. Right now it is outputting for every individual element in the s matrix.

When I run this program it runs through every single element and has an output for every number in the matrix. How can I make it give one output hwne its run?
function [] = Prgrm1(A,b)
s = rref([A,b]);
s1 = rref(A);
[m,n] = size(s);
s2 = eye(size(s1));
for w=1:m
for q=1:n
if s(:,1:end-1)==s2
disp('Unique Solution');
x=A\b;
disp(x);
elseif (s(w)~=0 || (s(w)==0 && s(q(:,end))==0))
disp('Infinitely Many Solutions');
t=s1(q(:,1:end))>=0
disp('Number of solutions:');
disp(t);
else
disp('No Solution');
end
end
end
end
What I'm getting looks like:
>> Prgrm1([1 0 1; 0 1 1], [1; 1])

t =

try using ";" after t=s1(q(:,1:end))>=0
