Hello, I have a problem with deleting rows in my multidimensional matrix. The thing is that I have a matrix A 800X1X100 with angles and i have to delete the rows that meet the condition. Here is my code:
for k=1:1:100
if(or(Z(k,1,:)>=230,Z(k,1,:)<=330))
Z(k,1,:) = [];
end
end
here is the error: A null assignment can have only one non-colon index.
Thank you.

The solution for your problem could be:
Z=rand(800,1,100)*400;
for(k=800:-1:1)
if(or(Z(k,1,:)>=230,Z(k,1,:)<=330))
Z((k-1)*100+(1:100)) = [];
Z = reshape(Z,[],1,100)
end
end
or use the squeeze function to make Z shape [800,100]
