matlab - How can I convert cartesian coordinates to polar coordinates using function -

i'm trying create function in matlab takes cartesian coordinate , converts polar.

function [homework5] = cartesian(x,y)  m = size(x,1)  n=1:m if x,y;  r=sqrt(x^2+y^2) theta=atan(y/x)   else disp('input incorrect')   end      if r > 10     disp('far origin') else     disp('close origin')   end  end 

i'm extremely new matlab , searches answer , reading tutorials e.t.c have proved futile.

i have converts 1 coordinate fine, need convert multiple coordinates @ once (hence forloop) can't it! user needs able enter array this: >>cartesian = [2,3;4,5;6,7] , have each row converted.

thanks help!

don't want use matlab's function cart2pol?

if inside this:

th = atan2(y,x); r = hypot(x,y); 

---

as code, has many issues syntax , logic.

first don't need loop. matlab designed work vectors , matrices. have use element-wise multiplication, delition , power .*, ./ , .^ operators.

also if x,y; doesn't anything. read doc how use if properly. preallocate m don't use it. function supposed return homework5, it's not defined in function's body. have read functions. make sure function saved file same name cartesian.m , in current directory or in matlab's path.
