Just speculating again, but I suspect that these four loops are prime
candidates for replacement by vectorization. Perhaps analyze() can be
modified to handle c_thd, r_thd, t_thd, b_thd as matrix/vector forms
of these variables. ndgrid may help with this:

[c_thd, r_thd, t_thd, b_thd ] = ndgrid( [c_thd_min:c_thd_st:c_thd_max]
, [r_thd_min:r_thd_st:r_thd_max] , [ t_thd_min:t_thd_st:t_thd_max] , [
b_thd_min:b_thd_st:b_thd_max] )
