besselk (Matlab function) Modified Bessel functions of the second kind

## Matlab/Scilab equivalent

Matlab | Scilab
    besselk
    besselk

## Particular cases

Scilab besselk function can work with only one output argument, but the Matlab function can work with two outputs arguments.

## Examples

Matlab | Scilab
    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
