INELLIPSE Locates points on the interior of ellipses. INELLIPSE(Z,KAPPA,LAMBDA,THETA,ZO) where Z is a complex-valued location Z=X+iY, and KAPPA, LAMBDA, THETA describe an ellipse at complex-valued position ZO=XO+iYO, is true if Z is inside the ellipse. KAPPA is the ellipse amplitude, LAMBDA is the linearity, and THETA is the orientation of the major axis with respect to the X-axis. KAPPA and LAMBDA are related to the semi-axis lengths A and B by KAPPA^2=(A^2+B^2)/2 and LAMBDA=(A^2-B^2)/(A^2+B^2). For details, see Lilly and Gascard (2006). __________________________________________________________________ Array or matrix input BOOL=INELLIPSE(Z,KAPPA,LAMBDA,THETA,ZO), where Z is a length M *row* vector, and the other input variables are length N *row* vector, returns an M x N boolean matrix BOOL. In this case the (m,n)th entry of BOOL is true if the mth location Z is inside the mth ellipse. If the input variables have the same number of multiple *rows*, say K, this is interpreted as corresponding to K different time. In this case BOOL will be a 3D array with dimensions M x N x K. __________________________________________________________________ See also ELLCURVES, ELLIPSEPLOT.
