Using 'ismember' against multiple sets of parameters

Hi there,
I'm trying to find two sets of parameters (Keeper_Indexes 1 & 2), and locate them on an image (Labeled_Image):
Keeper_Indexes1=find( 0.7 < para1 & para1 < 0.72);
Keeper_Indexes2=find( 0.9 < para1 & para1 < 0.905);
PossibleCracks1 = ismember(Labeled_Image, Keeper_Indexes1);
PossibleCracks2 = ismember(Labeled_Image, Keeper_Indexes2);
figure, imshow(PossibleCracks1,'DisplayRange', []),title('Possible Cracks1');
figure, imshow(PossibleCracks2,'DisplayRange', []),title('Possible Cracks2');
This is the current code i'm using, however, is there a way to integrate Keeper_Indexes 1 & 2 together, or to integrate two ismember functions into one? Meaning, figuratively,
Keeper_Indexes = find( 0.9 < para1 & para1 < 0.905) & find( 0.7 < para1 & para1 < 0.72);
TotalPossibleCracks = PossibleCracks1 + PossibleCracks2
Thank you for your help!

My guess is you can bypass both find() and ismember() with simple logical indexing.
Please post small example matrices (or explain how we can create sample matrixes) so that we can reproduce it.

Yes, you can combine the lines. Just do
Keeper_Indexes = [Keeper_Indexes1, Keeper_Indexes2];
PossibleCracks = ismember(Labeled_Image, Keeper_Indexes);
imshow(PossibleCracks>0); % Binarize and display.
