; Goal: wide and automatic tests of I/O of math functions in GDL
; Do the functions return arrays with good dims ?
;
; Very important remark : we DON'T reproduce the IDL bug
; in case on ([1], [N]) arrays, where IDL returns a [N] array
; where only the first value is OK (bug reproduced on IDL 5.4 to 7.1)
; We do return a [N] array with all values OK
; (in IDL, on contrary, case ([N],[1]) is well processed)
;
; testing the dimensions of Output of Mathematical functions like:
; -- family BESELI, BESELJ, BESELY and BESELK
; -- VOIGT
; -- BETA
; -- IGAMMA
; -- EXPINT
; ....
;
; It must be noticed that NO test on numerical values are done here.
; Please refer to dedicated tests (i.e. "test_voigt.pro")
