List of inverseTransform() Examples

Examples of inverseTransform()

ae.java.awt.geom.AffineTransform.inverseTransform()
Inverse transforms the specified ptSrc and stores the result in ptDst. If ptDst is null, a new Point2D object is allocated and then the result of the transform is stored in this object. In either case, ptDst, which contains the transformed point, is returned for convenience. If ptSrc and ptDst are the same object, the input point is correctly overwritten with the transformed point. @param ptSrc the point to be inverse transformed @param ptDst the resulting transformed point @return ptDst, which contains the result of theinverse transform. @exception NoninvertibleTransformException if the matrix cannot beinverted. @since 1.2
com.jhlabs.map.proj.Projection.inverseTransform()
com.opengamma.analytics.math.minimization.ParameterLimitsTransform.inverseTransform()
A function to transform an unconstrained fitting parameter (y*) to a constrained model parameter (y) - i.e. y = f^-1(y*) @param y Fitting parameter @return Model parameter
com.opengamma.analytics.math.minimization.SingleRangeLimitTransform.inverseTransform()
{@inheritDoc}
com.opengamma.analytics.math.minimization.UncoupledParameterTransforms.inverseTransform()
Transforms from a set of unconstrained fitting parameters to a (possibly larger) set of function parameters (some of which may have constrained range and/or be fixed). @param fittingParameters The fitting parameters @return The function parameters
edu.uci.ics.jung.visualization.VisualizationViewer.inverseTransform()
edu.uci.ics.jung.visualization.transform.BidirectionalTransformer.inverseTransform()
convert the supplied screen coordinate to the graph coordinate. @param p screen point to convert @return the graph point
edu.uci.ics.jung.visualization.transform.MutableTransformer.inverseTransform()
