How to group specific values i several vectors following a condition?

3 views (last 30 days)
Hi,
I am struggeling to find a method to extract values that comply with a specific condition from a vector.
The input is a random vector like x = [3,5,13,43,54,3,2,3,5,6,3,18,19,17,25.2,5,3,5,3,59,0,4,3];
I would like to extract the 'blocks' of values, that are e.g. greater than the value of 10.
The expected result would be: res1 = [13,54], res2=[18,19,17,25.2] and res3=[59]
The number of result vectors is not predetermined, as x is a random vector. The result would not have to be extracted as vectors, cells would be fine as well.
Thanks in advance!

hello
IMHO, according to the rules , the result should be : res1 = [13,43,54], res2=[18,19,17,25.2] and res3=[59]
and this is the code that achieve it :
x = [3,5,13,43,54,3,2,3,5,6,3,18,19,17,25.2,5,3,5,3,59,0,4,3];
%% main code
ind = (x>10);
p=find(diff(ind)~=0);
nb_of_blocks = length(p)/2;
for ci = 1:nb_of_blocks
ii = (1:2)+(ci-1)*2;
block{ci} = x(p(ii(1))+1:p(ii(2)));
end
