hey Guys, I have got a 1xn structure. Now i just want to write a code which can delete on column of a structure. For example:
A is structure with A.x / A.y /A.z This is a 1x5 structure. Now I want to make this a 1x4 structure by deleting the 3rd Column. So A(3) is gone and A(4) is now the new A(3) / A(5) is the new A(4)

A=struct('x',num2cell(rand(1,5)),'y',num2cell(rand(1,5)),'z',num2cell(rand(1,5)))
A(3)=[]

Your are right! If Check == 0 deletes one part of the structure, it exceedes the matrix dimension.

A=struct('UsedAmp',num2cell([1 2 3 4 5]),'OptimalAmp',num2cell([-1 2 3 4 -3]),'ClosestAmp',num2cell([0 2 3 4 -2]))
idx=[];
for u = 1:numel(A)
Check = A(u).UsedAmp + A(u).OptimalAmp + A(u).ClosestAmp;
if Check == 0;
idx(end+1)=u
end
end
A(idx)=[]

Or
A=struct('UsedAmp',num2cell([1 2 3 4 5]),'OptimalAmp',num2cell([-1 2 3 4 -3]),'ClosestAmp',num2cell([0 2 3 4 -2]))
A(squeeze(sum(cell2mat(struct2cell(A))))==0)=[]
