int im_minpos_vec( IMAGE *im, int *xpos, int *ypos, double *minima, int n );
 

DESCRIPTION

im_maxpos_vec(3) fills the arrays xpos and ypos with the x and y coordinates of the n pixels in the image im which have the highest values. It writes those values (at double-precsion) into the corresponding elements in the array maxima.
