How does Iradon and radon work?

Hi I'm a beginner, I've got a sinogram attach, and i'm not sure what i'm doing wrong with the following code, the data projections have been collected over 180 degrees. 1 degree per projection;
theta=0:1:179;
[R,xp]= radon(sinog_2,theta);
Dtheta=1;
filt=input( 'Filter?\n 1 = Gen-Hamming; 2 = Shepp-Logan; 3 = Ramp; 4 = none ');
switch( filt)
case 1
m_out=iradon(R,Dtheta,'Hamming');
case 2
m_out=iradon(R,Dtheta,'Shepp-Logan');
case 3
m_out=iradon(R,Dtheta,'Ram-Lak');
case 4
m_out=iradon(R,Dtheta,'none');
i feel like it is incomplete...
any help would be amazing Thanks!

Dtheta shouldn't be just one angle. The theta you use in the radon function is the same you should use in iradon.
