Re: Error: subscript indices must be either positive integers or logicals - For simple surf plot

[veryhappy]

function f(g)

for a=0:pi
        for b=0:pi
       
c(a+1,b+1)=tan(g*a) * arcsin(g*b);

        end
end

surf(c);

That should work but try:

function f(g)
  a=0:pi;
  b=0:pi;
  [aa,bb]=meshgrid(a,b);
  c=tan(g.*aa).*arcsin(g.*bb);
  surf(c);
endfunction

It should give you the same results with better perfomance
