Hi! I have two vector:

accel_x: 1 x 158479 (250 frames/s)

x: 1x16379 (60 frames/s)

This vectors correspond to the same time interval, wich is length(accel_x). How can I make the vectors the same size / sampling rate? I need to plot both vectors, to see their relationship through the time.

Many thanks!

在 MATLAB Online 中打开

"This correspond to the same time interval"

Does it?

>>t_accell = 158479 / 250  %duration of 158479 at 250 frames/s
t_accell = 
      633.916

158479 frames at 250 frames/s is 633.916 seconds of sampling

>>t_x = 16379 / 60
t_x = 
      272.983

16379 frames at 60 frames/s is 272.983 seconds of sampling

@Ines Domingos Data does not need to have the same sample rate to plot it against each other. You plot x data vs y data for each one so they can have different x data to each other if they cover a similar range, but as Guillaume comments, they do not appear to have anywhere near the same range.
