### copy vector of mat to vector of mat

(This is related to this )

I have a vector<Mat> src which is filled with data. It's size is src.resize( N )

I have another vector<mat> dest; I am declaring it's size to be dest.resize( N )

1) What is the right way to copy src to dest?Just dest=src?

2) If I want to copy to dest ,only the 1st row and all columns of src vector, then what size the dest vector should be?

dest = src;
src[0]( Range(0, 1),Range::all() ).copyTo( dest[0](Range::all(), Range::all() ) ); //for the 1st array of vector


If ,for example src is 4x4 , then ,since I want to keep only 1st row and all columns,the dest size should be 1x4. Is there a way to do this ?Using the src[0]( Range(0, 1),Range::all() ).copyTo( dest[0](Range::all(), Range::all() ) )?

Or,another idea , is to have the dest the same size with src ,but fill all the rest elements with zero for example?

=====UPDATE================

I figured this:

    dest[0] = src[0 ]( Range(0, 1),Range::all() );


for first row and all columns.

( I can't make it an answer yet ,but if there is another way please share )
