besselj (Matlab function) Bessel functions of the first kind

## Matlab/Scilab equivalent

Matlab | Scilab
    y = besselj(alpha,x)
    y = besselj(alpha,x,1)
    [y,ierr] = besselj(alpha,...)
    y = besselj(alpha,x)
    y = besselj(alpha,x,ice),ice = 1 or ice = 2
    // No equivalent

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