/*Class:csr
NAME: @code{dns} - dense matrix format
DESCRIPTION:
The class implements a float matrix in dense format.
A declaration whithout any parametrers correspond to a matrix with null size:
@example
dns<float> m;
@end example
The constructor can be invocated whith row, column:
@example
dns<float> m(nrow, ncol);
@end example
Notes that the constructor can be invocated with an initializer:
@example
dns<float> m = m2;
@end example
Explicit conversion is allowed from @ref{csr class}:
@example
csr<float> a = ...
m = dns(a);
@end example
Affectation from a scalar
@example
m = 3.14;
@end example
NOTE:
The @code{dns} class supports also a STL-like interface.
This interface is not yet stabilized.
