Eliminate Zero Spikes in Plot

A calculated curve (red, "brush contact force") is based on the smoothness of the original curves (blue, "brush position" and black, "shaft surface position"). Since oscillation in the original curves will lead to "Zero" values in the red curve the plot has areas including spikes down to 0. How can I eliminate those "zero" spikes in brush contact force data keeping the upper curve shape? Only the upper curve shape is needed for further analysis.

Hi Jörg,

if possible, please provide example data so that we can try our suggestions. Two thoughts I would try:

• rmoutliers
• movmax, and then removing duplicates

Best wishes,

Hey Harald,

I attached the file with the curve data.

I'll check on rmoutliers and movmax.

Regrads,

Hi Jörg,

Fc.mat seems to just contain a logical array Fc_. It's not clear to me how this relates with the plot.

Oh sh..., sorry. Forgot to put the time in.

Now it should work.

Thanks a lot!

Hi Jörg,

in this case, it's actually sufficient to just remove the rows with 0 in the second column:

Fc_(Fc_(:,2) == 0, :) = [];

Best wishes,

Harald
