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
