corrfunctline
algorithm
- calculates 2-point longitudinal velocity correlation coefficients
- along several lines of the domain
- from distance 0 to distance length(X)
- calculates mean of the results of all lines
- calculates integral length scale
- plots correlation function
syntax
[meanrhok,L]=corrfunctline(x_velocity,X)
