# How do I know if a perspective matrix is right or left handed coordinate system?

For example, if I define my perspective matrix as the following:

m[0]  = 1.f / ( aspect * focalLength );
m[5]  = 1.f / focalLength;
m[10] = -zFar / (zFar - zNear);
m[11] = -1;
m[14] = -(zFar*zNear)/(zFar - zNear);


How can I tell if my perspective matrix is right or left handed coordinate system?
