Finding closest value in data table
显示 更早的评论
1) I want load large amount of experiment data (distance for x-axis, velocity for y-axis).
2) Find and load the closest to 1m on the x-axis, and also the corresponding the velocity in y-axis.
3) Find and load the closest to 2m on the x-axis, and also the corresponding the velocity in y-axis.
4) Find and load the closest to 3m on the x-axis, and also the corresponding the velocity in y-axis.
I want to rearrange the experiment data with regular intevals as above.
Please help..

Hints:
data=[0.52299 0.000237
1.04598 0.041598
1.56897 0.005755
2.09196 0.012987

9.413818 1.127799
9.936808 0.429399
10.459798 0.814943];
Next: Distance for x-axis, velocity for y-axis
x_distance=data(:,1);
y_velocity=data(:,2);
Next: "Find and load the closest to 1m on the x-axis, and also the corresponding the velocity in y-axis."
What does the 1m menas?
Is that closset between x_distance & y_velocity?? If so, then
close_1m=x_distance-y_velocity;
Then finding the correcponding index
idx=find(close_1m==min(close_1m))
Please do the rest part by yourself.
:)
