Enumeration Type Documentation

enum vil1_convolve_boundary_option

Available options for boundary behavior.

When convolving a finite signal the boundaries may be treated in various ways which can often be expressed in terms of ways to extend the signal outside its original range.

Enumerator:

vil1_convolve_no_extend
vil1_convolve_zero_extend
vil1_convolve_constant_extend
vil1_convolve_periodic_extend
vil1_convolve_reflect_extend
