I've read some matrix documentation (see below) and did not experience any difficulty in compiling codes:
http://www.boost.org/doc/libs/1_42_0/libs/numeric/ublas/doc/matrix.htm
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
