Manipulating Cell arrays element

Say I have a cell array called aa. Inside the cell I have 5 data elements [in reality it is huge matrix]. That 5 data element is for green and red light.

green light =1;

red light = 2;

aa index is same as ss. Means the first data element in aa is for green light, the second data element is for red light and so on.

I want to make the aa cell in such a way that it contains only for green light data element.

Can any one help me ?

Thanks in ADVANCE!!!!

aa = {rand(280,3) , rand(280,3),rand(280,3),rand(280,3),rand(280,3)};
ss = [1  2  1  2  1]; % Matrix for Green and Red light

We need a shrunken-down example, showing the input and desired output.

desired output:

aa = {rand(280,3) Null rand(280,3) Null rand(280,3)}

Null = Red light data that I want to ignored.

so, aa contains only green light data

@Amit Chakraborty: Are you aware, that "Null" is no standard syntax in Matlab? Should the readers understand this e.g. as [] ?

[Amit Chakraborty]

@Jan, Yes you are correct. I want to mean that reader should take

Null = [ ]

aa(ss==2)={[]};
