Here is my matlab source code:
real = [
.00000
.00297
.01098
.02174
.03242
.04047
.04407
.04220
.03448
.02099
.00208
-.02177
-.05000
-.08204
-.11731
-.15528
-.19538
-.23712
-.28000
-.32354
-.36727
-.41077
-.45361
-.49538
-.53571
-.57424
-.61061
-.64452
-.67568
-.70381
-.72869
-.75010
-.76786
-.78184
-.79190
-.79797
-.80000
]

imag = [
.00000
.08657
.16917
.24485
.31211
.37077
.42149
.46524
.50296
.53544
.56325
.58677
.60622
.62170
.63326
.64089
.64458
.64428
.64000
.63172
.61947
.60328
.58323
.55943
.53199
.50107
.46686
.42956
.38940
.34665
.30158
.25449
.20568
.15549
.10425
.05230
.00000
]

c = complex(real, imag)
% plot(real, imag, 'b')
plot(c, 'b')
axis([-.8 0.1 0 .8])
title('\alpha = 10')
xlabel('Re(h\lambda)')
ylabel('Im(h\lambda)')
set(gca, 'YAxisLocation', 'right')
set(gca, 'Box', 'off')

What I wanted was to shift Y AXIS left 0.1 unit, so (real, imag) = (0.0, 0.0) can crossing.

thanks,

currently not possible...
there are a few FEX submissions, which (try to) deal with this...

Why are you using function names as variables?

help real
help imag

Hope this helps.

Greg,
I changed to rea and ima.
The code like:

c = complex(rea, ima)
d = rea + ima * i
% plot(rea, ima, 'b')
% plot(d, 'b')
plot(c, 'b')
axis([-.8 0.1 0 .8])
title('\alpha = 10')
xlabel('Re(h\lambda)')
ylabel('Im(h\lambda)')
set(gca, 'YAxisLocation', 'right')
set(gca, 'Box', 'off')

Still does not work.

thanks,
William

US,
what do you mean by "FEX submissions"? since I am new to this forum.
Could you point me the URL link(s)?

thanks,
William
