Multilevel Helix

Actually I had this script beacuse an accident, when I was trying to make an equipotential line in order to modeling a geoelectrical method. but I found that my fail in this script can make it looks like a multilevel helix

phi = 3.14;

k=1;

for m = n:n:r;

    i(k)=m;

    k=k+1;    

end

V = ((I*rho)/(4*phi))*(1./i);

a = [0:1:360];

for p=1:length(i);

    x(:,p) = i(p)*cos(a.*pi/180);

    y(:,p) = i(p)*sin(a.*pi/180);

    z(:,p) = linspace(0,100,length(a));

end

figure 

for nl=1:length(i);

    plot3(x(:,:,nl),y(:,:,nl),z(:,:,nl))

    %text(x(1,nl),y(1,nl),[num2str(V(nl),2)])

    %title(‘Nilai equipotential pada tiap lintasan’)

    hold on

    grid on

end

phi = 3.14;
k=1;for m = n:n:r;    i(k)=m;    k=k+1;    end
V = ((I*rho)/(4*phi))*(1./i);
a = [0:1:360];
for p=1:length(i);    x(:,p) = i(p)*cos(a.*pi/180);    y(:,p) = i(p)*sin(a.*pi/180);    z(:,p) = linspace(0,100,length(a));end
figure for nl=1:length(i);    plot3(x(:,:,nl),y(:,:,nl),z(:,:,nl))  

 %text(x(1,nl),y(1,nl),[num2str(V(nl),2)])    

%title(‘Nilai equipotential pada tiap lintasan’)    hold on    grid on

end

Installing Google Skecth Up on Windows 7

 

I Don’t know what can I do when Iam stuck installing some programs in my windows 7. I think that previous version of windows (XP) is the most compatible.
Actually I almost desperate and going to install dual OS in order to install some programs in my laptop.

like ArcGis 9.2, I found that in windows 7 it can’t run. finally, It is no problem when my friend accomodates me by bought ArcGis 9.3 that running well in windows 7. problem fixed.

I got a problem again,  when I was installing google sketch up. I found that an error occured before the installation finished. However I must find the solution , and I start googling. In hours, I found that the error message that say’

” An error occurred during the installation of assembly ‘Microsoft.VC80.ATL,type=”win32″,version=”8.0.50727.4053″,publicKeyToken=”1fc8b3b9a1e18e3b”,processorArchitecture=”x86″‘. Please refer to Help and Support for more information. HRESULT: 0x800736FD.

“

can be fixed with registry editor.Actually I don’t know what the message means, but in my searching i found that error caused by “running out registry space”.

so the step for solution is :

1. go to registry editor

2. find the HKEY_LOCAL_MACHINE\System\CurrentControlSet

3. Increase the registry space by changing value 5d00000(in hex) which is 97517568 to value fffffffff (in hex value).

I restart my machine, reinstall google sketch up and finally… it works. Thaks to my reference for it’
