graph multiple fields in a struct
显示 更早的评论
I have a struct with multiple fields named data1, data2, data3 etc up to 9 I want to graph the first two colums of each field
I used this
position = variable.data1(:,2);
velocity = variable.data1(:,3);
%then i did
plot(position,velocity)
This worked fine but is there anyway to do this in a loop to make it faster? In the future I may have data up to 100s of different arrays

fld = fieldnames(variable); %list of all field names.. data1, data2,data3...
for i = 1:numel(fld) % for each field name
m = variable.(fld{i}); %this will be the data1,data2,data3 matrix
pos = m(:,2);%index matrix for position
vel = m(:,3); %velocity
plot(pos,vel); %plot results
hold on; % keep plot for next plot
end
