Details:

I do homework, and I find error:
 ** On entry to ZLASCL parameter number  4 had an illegal value
error: func541: exception encountered in Fortran subroutine zgelsd_
error: called from
    func541 at line 74 column 8
    No541 at line 82 column 5
error: evaluating argument list element number 2
error: called from
    No541 at line 82 column 5

where

line 73   |function Fx = func541(X)
line 74   |    Fx = ((X / (log10(X - 1).^4)) - 3) ;
line 75   |end

line 81   |     X = -10:0.001:10 ;
line 82   |     plot(X,func541(X))

(It's in No541.m)
I don't now, where mistackes, maybe my code have mistackes.



double octave dropped without an error message.
(This was done no51.m program)
