saving specific column with all elements from 4 to 5 different matrices in matlab GUI

Hi,

I want to save all elements of some specific columns from 4 to 5 different matrices in such a way that all selected coulmns with all elements will save in one array. For this purpose I made a GUI in that from browse button I select a big matrix (let say big matrix 1) and then from edit box I write down the column number one by one and press submit button and save all those selected coulmn with all elements I stored into array.

Now the problem is that, Again I will select some different big matrix (let say big matrix 2)and similarly I want to save all elements of some specific coulmns and want to store in the same array in which I previously stored elements of selected columns from big matrix 1.

its like I select some columns from matrix 1 and also select columns from matrix 2 and concatenate both of them in single array.

Can anybody help me what should I do

Which aspect of it is causing the problem?

There are two posibilities I am thinking off but unable to implement them or there any other way to do that

One: Array concatenation

I select one big matrix (let say matrix 1) and I select few coulmns from it with all elements and save them in a array. Then again I select another big matrix (let say matrix 2) and again I select few coulmns from it with all elements and then save them in same array

Two: Generating a cell array

I select one big matrix (let say matrix 1) and I select few coulmns from it with all elements and save them in a cell array. Then again I select another big matrix (let say matrix 2) and again I select few coulmns from it with all elements and then save them in same cell array

Muhammad - if your "big matrices" have different number of rows, then use a cell array to manage all of the columns that you extract from your matrices.
