rect2polar, rectangular to polar, complex number

[jm-ZOGG]

Hello

Has the function rect2polar(Z) been removed in Version 4.0?
This function was used to convert complex number from rectangular form
to polar form.
Im my new version Scilab 4.0 it doesnt work.

Many thanks for your answer

let's see if this helps you:

function [r,th]=rect2pol(x,y)
//rectangle to polar coordinate conversion
//based on "Scilab from a Matlab User's Point of View", Eike Rietsch,
2002
r=sqrt(x^2+y^2);
th = atan(y,x)*180/%pi;
endfunction

function [r,th]=cr2pol(a)
//complex number rectangle to polar conversion above
[r,th]=rect2pol(real(a),imag(a));
endfunction

-->[mag,ang]=rect2pol(1,1)
ang =

45.
mag =

1.4142136

-->c=0+1*%i
c =

i

-->[mag2,ang2]=cr2pol(c)
ang2 =

90.
mag2 =

1.
