how to map in matlab

Hello is there any command in matlab to map a set of point from one boundary to another. for instance we choose a set{(x_i,y_i)} on boundary of a rectangle [0,1]*[0,1], and we want to find new{(X_i,Y_i)} on for instance a curve: x=A*cos(t)+B*cos(t*((A/B)-1)); y=A*sin(t)-B*sin(t*((A/B)-1)); Thanks anyone very much, By the way this site is a great help for me, because of having skilful and nice members.
