Two conditional operations can be used in matlab or do I need to use double if?

2 views (last 30 days)
for i = 1:length(beam_spalling.high)
if transversal(i) == 0 && ongitudinal == 0
severity_bs(i) = 2;
elseif transversal(i) == 0 && longitudinal > 0
severity_bs(i) = 3;
elseif transversal(i) > 0 && longitudinal == 0
severity_bs(i) = 3;
else transversal(i) > 0 && longitudinal > 0
severity_bs(i) = 4;
end
end
For the third conditional, could be used another loop to have one or another option?

It looks like you could use a lookup table and skip the entire loop:
transversal=[0 1 0 1];longitudinal=[0 0 1 1];
LUT=[2 3;3 4];
[~,ind1]=find( [transversal(:)==0 transversal(:)>0 ] );
[~,ind2]=find( [longitudinal(:)==0 longitudinal(:)>0] );
severity_bs=LUT(sub2ind(size(LUT),ind1,ind2))
severity_bs = 4×1
2 2 4 4
Note that you have a typo in your second line: it is missing an l.
