Remove values from cell array

Hi all

   array1 =  {[1,2,3,6,7,8];[1,2,6]}
   array2 =  {[3,6,7,8];[1,2,6]}
   Remove = {[0.94,1,0.5,0.90,1,0.87];[1,0.9,1]}

Values in array1 corresponds to each value in 'Remove' e.g. 1 corresponds to 0.94, 2 corresponds to 1 and so on. In array2 i have removed some values from array1 based on a condition. Like 1,2 are removed from array1{1,1} where as no value is removed from array1{2,1} (result shown in array2)

Now I also need to remove corresponding values from 'Remove' which are removed from array1. Like 1,2 are removed from array1{1,1} so 0.94 and 1 will also be removed from 'Remove'. Result will look like this:

    ResultantArray = {[0.5,0.90,1,0.87];[1,0.9,1]}

Please help.

Consider you save the index of the first two values deleted from array1 as follows:

idx=find(array1{1,1}(1:2));

Then, delete the first two corresponding values from Remove as follows:

Remove{1,1}(idx)=[]

Thank You. What if values deleted are 4 and 8. I mean not continuous as 1 and 2?

[Birdman]

Well, to generalize it, you may use ismember function as follows:

[~,idx]=find(ismember(array{1,1},[4,8]));

Thanks alot.
