Graph is blank. Why?

mmf_data = dataeren(: ,1) ;

flux_data = dataeren(:, 2) ;

V = 8000*sqrt(2) ;

NS = 1000 ;

freq = 50 ;

w = 2*pi*freq ;

time = 0:1/3000:1/30 ;

flux = -V./(w*NS)*cos(w.*time) ;

mmf = interp1(flux_data, mmf_data, flux ) ;

im = mmf/NS ;

irms = sqrt(sum(im.^2 )/length(im));

subplot (2 , 1 ,1) ;

plot (time , im) ;

title (' \bf50 Hz için Mıknatıslanma Akımı ');

xlabel ('\bfZaman (s) ' ) ;

ylabel ('\bfIm(A)') ;

axis ([O 0.04 -2 2]) ;

grid on ;

My graphs is blank. When i change V value to 325, graphs work but i need work on 8000*sqrt(2)

We can't run this as we don't have dataeren.

If you call disp(size(im)), what does it say?

[Stephan Ciobanu]

you can try to specify the interpolation method:

mmf = interp1(flux_data, mmf_data, flux ,'pchip')

% or

mmf = interp1(flux_data, mmf_data, flux ,'spline')
