Sorry to be so obtrusive, but I need help!!! Thanks!
~~~~~~~~~~PROBLEM STATEMENT:
I have actually two problems.
-> My .m file does *not* pause when it comes to the "pause"
statement. Why is this?
-> plot gives me an error where there is no error.
***********
~~~~~~~~~~FUNCTION WHICH CAUSES PROBLEM:
Here is the function:
function plottrack(x)
[slices,values] = size(x)
for i = 0 : ((values-3)/6)-2
i
pause
plot(x(:,(i*6)+4),x(:,(i*6)+5))
pause
endfor
endfunction
************
~~~~~~~~~~~OUTPUT:
Here is the output:
octave-3.4.0:2> plottrack(snaps)
slices = 31
values = 183
error: plottrack: A(I,J): column index out of bounds; value 183 out of bound 183
error: called from:
error: /Users/johns/Programming/diameter/plottrack.m at line 4, column 4
octave-3.4.0:2>

Ben also asked,
octave-3.4.0:4> which plot
`plot' is a function from the file
/Applications/Octave.app/Contents/Resources/share/octave/3.4.0/m/plot/plot.m

~~~~~~~~~~HISTORY:
Ben recommended I try this and I still get an error:
octave-3.4.0:3> plottrack(rand(31,183))
slices = 31
values = 183
error: plottrack: A(I,J): column index out of bounds; value 183 out of bound 183

Dima had the following comment:

>>John -- does the following code work on your machine ?

But this works, b is 200:
