Not quite sure what you really want, but here is a start:

ci = [0.9 0.95 0.99 0.999];
c  = [1.645 1.960 2.576 3.291];
b = false;
while( ~b )
    x = input(['Pick a number from ' num2str(ci) ' : ']);
    [b,k] = ismember(x,ci);
    if( b )
        break;
    end
    disp('Number selected is not valid');
end
result = c(k);
