Level Crossing Rate

The function calculates Level Crossing Rate (LCR).

Description

LCR calculates Level Crossing Rate, that is a number of crossings (in the positive direction) of an input vector through a given threshold vector.
[x,t] = lcr( sig, thr );

The crossings are calculated for all the values of the input threshold vector. The input signal has to be a vector.

Example:
n = randn( 1, 1000 );
x = lcr( n, -5:0.1:5 );
plot( t, x );

Good work.

[H. S. Kim]

good to see this

So powerful! Really a nice work.

Please use the following number calculator to save more than 10% CPU time when you have a very long vector:

lcf( i ) = length(find(tmp==1));

Thanks again! I happened to find your code, but it will help my research from now on.
