create_path_regular.c

Example showing how to create a simple scan path, based on regular matrix of points. This is a model function for further non-equidistant path creation; so this function itself does not do anything that one could not do manually. Function decides how many points will be necessary (here only on basis of requested x and y resolution), allocates arrays of doubles for storing the locations which microscope should follow and fills the arrays with requested values.
