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