Some one gave me this code to implement but I am not able to understand what Line 8 does in the code below. What does this mean y(y
clear;
lambda=0.1;
T=100;
M=50;
for i=1:M
x=exprnd(1/lambda,1,2*lambda*T);
y=cumsum(x);
pp{i}=y(y<T);
end
If line 8 is pp{i} = y(y < T)
, then it's creating a "cell array" (so now you can google it) with the {}
syntax and setting element i
to all the values in y
that are less than T
(i.e. 100)`. That is:
y<T
is an array the size of y
with 1
in the places where the corresponding element of y
is less than T
.
y(y<T)
is then selecting only those elements. So it is probably smaller than y
, and all the entries are less than T
.
And then:
pp{i} = y(y<T)
is assigning that array to element i
of a "cell array". Cell arrays are like normal arrays except that each element can be a different type or a different size.
