Spatio-temporal diagram

ST = spatiotempf(F, X, Y), where F is an array of scalar fields, 
returns a spatio-temporal matrix ST(M,N), in which each line M is given 
by the value of F(M) taken along the line(s) joining the points X,Y, 
specified in physical units (eg., in mm). To specify a single line 
from (x0,y0) to (x1,y1), use X = [x0,x1], Y = [y0,y1]. 
ST = spatiotempf(F) allows the user to select lines using the mouse 
(double-click to finish line selection). 
[ST,X,Y] also returns the selected lines. 
The value of the field along the lines is interpolated using Matlab's 
function INTERP2.
