RE: an array with negative index

[Hall, Benjamin]

I'm not sure I understand.  Is the following not what you are trying to do?


coeff = -4:4;
hits  = [0 5 9 12 17 18 13 5 1];

bar( coeff, hits );

# or 

plot( coeff, hits, 'o-' );

# or maybe the following is more relevant

ii = find( hits == 18 );

plot( coeff(ii), hits(ii), 'o' )

Subject: an array with negative index


Hi,

I wish to plot a distribution that could look like:
coefficient value: -4  -3  -2  -1  0  1  2  3  4
number of hits:    0    5   9  12  17 18 13 5  1

since an array starts at 1, I can't possibly store the "number of hits" with
an
index corresponding to their "coefficient value".
If I switch the coefficient values by a value starting at 1 (i,e. instead of
-4,...4, it would be 1...9) then when I plot the array I don't see the
relevant
coefficients (in the abscissa ordinate) because of the switch.

Is there a way to get around this problem ?

Thanks,

Jean-Michel
