Dear all
I've read some matrix documentation (see below) and did not experience any
difficulty in compiling codes:

However I am using SQL API to query data from c++, and wondering how I can
build a boost price matrix.
*Ps*: table contains 3 columns: name (*string* type), date (*datetime*
type), price (*double* type)

1/While retrieving the query data, my screen output is as follows:

aaaaa 2014-12-22 30.1
aaaaa 2014-12-21 27.7
bbbbb 2014-12-22 13.2
bbbbb 2014-12-21 10.3
ccccc 2014-12-22 80.4
ccccc 2014-12-21 79.9

2/My aim is to create a following price matrix (here 2 by 3) as:

30.1 13.2 80.4
27.7 10.3 79.9

Thanks in advance and Regards
