Hi Ralf
That's fantastic!
Thanks for the info.
Cheers

Hello Yajima,
just a remark: you can access the component (k,l) of the i-th matrix A(i)
directly by, e.g.
A(i)(k,l) = 1.0;
So, it's not necessary to introduce 'local' matrices b and/or c. But it's
not wrong to do so.
Bye
Ralf

That is exactly what I was looking for.
Your code worked perfectly.
Thank you so much!

Hello Yajima,
you can do something like
ublas::vector<ublas::matrix<double> > A;
I.e.:
ublas::vector<dmatrix> A;
A.resize(10); // vector containing 10 ublas::matrices
for( int i=0;i<10;i++){dmatrix b(10,10);set values to b;
// set the correct size of matrix A(i)
A(i).resize(b.size1(), b.size2());
A(i) =b;}
That should work ... (not tested)
You can use also:
std::vector<ublas::matrix<double> > A;
or
std::map<int, ublas::matrix<double> > A;
or other containers ...
Depends what you prefer ...
Bye
Ralf

Is there away to create a "set" of ublas matrix.
(by set I mean it in the most abstract way)I would like to create bunch of matrix<double> and store it in some form of a data structure
then retrieve them by an index and use it as a matrix<double>.
Here is a vague pseudo code for what I would like to do
something A;for( int i=0;i<10;i++){dmatrix b(10,10);set values to b;A(i) =b;}
//then use it as
for( int i=0;i<10;i++){dmatrix c = A(i);do calculation with c}
Or if you have better way to do something similar, I'd appreciate your input.
Thank you for your help.
CheersYajima
