How can I create a dynamical cell array?

Hi everybody,

I'm trying to analize some data and I need to create a helpful data structure. The data are stored into 2 vectors: the first one is composed by integers, whereas the other one by double (they are times). Now I want to detect the some integers related to the second array by subdividing the time into ranges.

For example:

firstVector=[1, 2, 4, 3, 8, 9, 10, 11, 2, 3, 15, 7, 4, 2, 1];
secondVector=[1.23, 1.35, 1.74, 2.1, 2.2, 2.5, 2.8, 3.11, 3.24, 3.47, 4.5, 4.7, 4.8, 5.0, 5.5];
indxRanges=[0,2,3,4,5,6];

Assume that I want to detect in which order the integers 1,2,3,4 occur in the ranges by evaluating the related times.

For the above example, for the range [0,2] we will obtain 1,2,4 for the range [2,3] we will obtain 3 and so on.

NB: in some ranges these integers might not occur.

Now, I think the best solution to store these data is a cell array. But, How can I create it dynamically?

Thanks!

I do not understand the question. What does this mean:

 detect the some integers related to the second array by subdividing the time into ranges.

? And what is "evaluate" and "related" in "evaluating the related times"?
