a=[10,14,5,6,7,19]
in this array need to build an array a[] again but the value should not be less than or equal to 15 i need it
a=[24,18,19]
when i shift the value after adding my value which i have already added remain in the array like this
in 1st loop i have result lke this
a=[24,5,6,7,19,19]
how to get the right result with shifting

a = [10, 14, 5, 6, 7, 19];
r = zeros(size(a)); % Pre-allocate maximal length
ri = 0;
q = 0;
for k = 1:length(a)
q = q + a(k); % Accumulate values of "a"
if q >= 15 % Flush accumulated value:
ri = ri + 1;
r(ri) = q;
q = 0;
end
end
r = r(1:ri); % Crop unused values

@kpreet: Is this a serious question? What about adding this line at the end:
a = r;
Or you can do it "inplace", but the modifications are such tiny (changing all "r" to "a" and "ri" to "ai"), that I'd actually assume, that you could solve this by your own:
a = [10, 14, 5, 6, 7, 19];
ai = 0;
q = 0;
for k = 1:length(a)
q = q + a(k); % Accumulate values of "a"
if q >= 15 % Flush accumulated value:
ai = ai + 1;
a(ai) = q;
q = 0;
end
end
a = a(1:ai); % Crop unused values
It would be a kind idea to explain, if at least the values of "r" match your expectations.
