[eigen] matrix / scalar

[Andy Somogyi <andy.somogyi@xxxxxxxxx>]

Hey Guys,

what do you think about adding some operators to ease operating on a matrix with a scalar, i.e. what I'm thinking about is something like:

MatrixXi mat = ...;

// set all matrix values to scalar
mat = 1;

// add scalar to all matrix values
mat = mat + 1; // or optionally
mat += 1;
