Check max value of an array against a constraint

hi i have the following matrix

a=  1  1   1

    5  0.6 1

    2 0.5 0.9

how would i find the maximum value that is not > or = to 1 so in this case 0.9. Additionaly the matrix can be various dimensions.is it possible using the max command if not how would i approach this problem?

max(a(a<1));

and index of the location

a1 = a;
a1(a1<1) = -inf;
[value,i1] = max(a1(:));
[ii,jj] = ind2sub(size(a),i1);
out = [value, ii, jj];
