Re: vector function within vector function

[ken1866]

I think I understand the error message now.  Since each variable is assumed
to be a matrix, p2 will clearly be incompatible with x.  Does this mean I
have no choice but to use a for loop (like below)?

num=200;
b1=linspace(200,225,num);       
b2=linspace(0.33,1.0,num);              
[xx,yy]=meshgrid(b1,b2);

function val=ls(p1,p2)
  val=0;
  x=[1,2,3,5,7,10];
  y=[109,149,149,191,213,224];
  #val=sum((y-p1.*(1-exp(-p2.*x))).^2); #<== nonconformant arguments (op1 is
200x200, op2 is 1x6)
  for i=1:6
    val+=(y(i)-p1.*(1-exp(-p2.*x(i)))).^2;
  end
endfunction

z=ls(xx,yy);
