Bessel functions of the second kind
bessely
Scilab bessely function can work with only one output argument, but the Matlab function can work with two outputs arguments.
y = bessely(alpha,x) y = bessely(alpha,x,1) [y,ierr] = bessely(alpha,...)
y = bessely(alpha,x) y = bessely(alpha,x,ice),ice = 1 or ice = 2
