% Compute the focal length from angle of view. If the imaging element is 2-dimensional it will compute two f. Type FocalLengthFromAngleOfView for a demo. ------------------------------------------------------------------------ Form: f = FocalLengthFromAngleOfView( alpha, d ) ------------------------------------------------------------------------ ------ Inputs ------ alpha (2,1) Angle of view (rad) d (2,1) Dimensions of film or imaging chip ------- Outputs ------- f (1,1) Focal length ------------------------------------------------------------------------ Reference: http://en.wikipedia.org/wiki/Angle_of_view ------------------------------------------------------------------------
