plot(a,b,'r*','Markersize',1);
xlabel('Epoch')
ylabel('PRN')

Hello
I have plot a signal in which i am getting some interruption. Plot is of total number of visible satellite on y-axis and total number of epoch on x-axis. So I am getting graph as attached.

The variables you're plotting are 'a' and 'b'. Check for NaN values in both using isnan().

There is no gap or NaN in the data so it is difficult plot it.
How can I do it and please find the attachement of a and b ? I think you are giving my right direction and I am not able to fidure it out.

There are no NaN's in the data. To get the breaks/ interruption you can get the successuve distances and find the ditances which are greater then the resolution.
a, b are your point arrays.
da = diff(a) ;
db = diff(b) ;
d = sqrt(da.^2+db.^2) ;
iwant = nnz(d>1) ; % I assume if the points are continuous the distance should be 1.
