The MathTransform class represents a mathematical transformation that can be applied to CoordPoints. GeoCalc supports several types of MathTransforms, which are outlined in the ClassType enumeration. There are two ways to define a MathTransform.
There first way is to set the various Parameters and Settings needed by the specific type of MathTransform. A description of the Parameters and Settings needed by each type of MathTransform can be found by clicking on the appropriate description from the ClassType enumeration page.
The second way that a MathTransform can be defined is by using the AddPoint and AddPointList methods to add a set of control and observed points for the transform. A control point is a point in the domain of the MathTransform, which can be viewed as a source point or a point that has not yet passed through the MathTransform. An observed point is a point in the codomain of the MathTransform, which can be viewed as a target point or one that has passed through the MathTransform. Once a list of control and observed points has been added, the Solve method is used to find the Parameters and Settings that define the MathTransform from the control points to the observed points.
