Suppose
dataI = [100;200;300;100;200;300];
limit = 150;
if any(dataI >= limit)
disp('There is at least one value above the limit.')
DataI_with_Neg = dataI - 100; %% Here I want to sub 100 from all the values which are higher than limit = 150 and get new data after sub%%
else
disp('All values are below the limit.')
end

https://blogs.mathworks.com/loren/2013/02/20/logical-indexing-multiple-conditions/ - this should get you started
DataI_with_Neg = dataI(dataI > limit) - 100;
% ^^^^^^^^^^^^^^^--- add this (datas which are higher than 150)

Data_higher_than_limit = dataI(dataI > limit)
Data_higher_than_limit_subtracted_by_100 = dataI(dataI > limit) - 100

loc = dataI >= 150;
dataI(loc) = dataI(loc) - 100;

Perhaps this?:
>> dataI = [100;200;300;100;200;300]
dataI =
100
200
300
100
200
300
>> limit = 100;
>> idx = dataI >= limit;
>> dataI(idx) = dataI(idx)-100
dataI =
0
100
200
0
100
200
