You don't have IMSL, but you do have GSL (in Linux 64 bit):

function ai, x
return, call_external('/usr/lib64/libgsl.so', 'gsl_sf_airy_Ai', double(x[0]), 1l, /all_value, /d_value, /auto_glue)
end

pro test_ai ; Ai(x) in [-5,5]
x=dindgen(1001)/100-5
y=x
for j=0,1000 do y[j]=ai(x[j])
plot, y
end

Feel free to add error checking :-)

regards,
Lajos
