How can i speed up this procedure? It steps through a matrix of either
64x64x64, 128x128x128 or in the worst case 256x256x256.

<==BEGIN IDL==>
FOR i = init, limit, 1 DO BEGIN
FOR j = init, limit, 1 DO BEGIN
FOR k = init, limit, 1 DO BEGIN
X=img_a(i:kernel_dim+i,j:kernel_dim+j,k:kernel_dim+k)
Y=img_b(i:kernel_dim+i,j:kernel_dim+j,k:kernel_dim+k)
sign_prob_map=TM_TEST(X,Y)
spm_plot_statistic(i,j,k)= sign_prob_map(0)
spm_plot_significance(i,j,k)= sign_prob_map(1)
ENDFOR
ENDFOR
ENDFOR
<== END IDL ==>

Thanks in advance,

Bob
