hello i try to make a for loop but i need the jumps between the numbers will be in factor of 10 lets say there is a for loop like that: for i=1:5
so i need to make
for i=10,100,1000,10000
but it wont work maybe someone know what to do? thanks alot!

for ii = logspace(1,5,5)
% Do stuff here.

for ii = 10.^(1:5)

w=0:60*(10^6/4096)+1:60*10^6 ; % [Hz]
zl=50 ; % [ohm]
zs=50 ; % [ohm]
R=1.9884 ; % [ohm/meter]
G=0.01686*10^-9 ; % [mho/meter]
C=0.13394*10^-9 ; % [farad/meter]
L=362.81*10^-9 ; % [henrry/meter]
zc=sqrt((R+1j.*w.*L)./(G+1j.*w.*C)); % characteristic impedance
gama=sqrt((R+1j.*w.*L).*(G+1j.*w.*C));
l_change = 10.^(1:5);
%Engine
lg = (l_change')*gama;
aa=cosh(lg);
bb=bsxfun(@times,zc,sinh(lg));
cc=bsxfun(@times,(1./zc),sinh(lg));
dd=cosh(lg);
H_change= (zl./((aa.*zl)+bb+(cc.*zl.*zs)+(dd.*zs)));
EDITED: per Oleg's comment and full data set.

Doesn't work with complete code, bsxfun is needed

@Oleg and Andy,
Also, as people comment on non-Answers, it is harder for the editors to move the answers to the appropriate comments section...
Perhaps this will be fixed in the future, but right now editors cannot edit comments, only delete them, and cannot change an answer to a comment with the same authorship...

@Oleg, thanks!
@Matt, good to know. In the future, I'll make this sort of comment on the main question so that the 'answer' can be edited appropriately.
