Function Documentation

std::vector<arma::vec2> rotate(const std::vector<arma::vec2> points, double angle)

Rotates a vector of 2D points by a specified angle.

This function takes a vector of 2D points and rotates each point around the origin by the given angle (in radians). The rotation is performed using a standard 2D rotation matrix, being counterclockwise if theta is negative.

Parameters:

• points – A vector of 2D points (arma::vec2) to be rotated.

• angle – The angle of rotation in radians.

Returns:

A vector of 2D points after rotation.
