I can’t run the code.
However it’s obvious that ‘f’ needs to be a vector in order to plot anything other than the markers. Create it as a vector by subscripting it (as ‘f(i)’), then put the plot calls after the loop.
The entry into the loop needs to be —
iv = 1:i;
for i = 1:numel(iv)
. . . CODE . . .
end
then in the loop —
f(i) = fnew;
So for example —
i = 10;
iv = 1:i;
for i = 1:numel(iv)
f(i) = exp(-0.5*i);
end
figure
plot(iv, f, '-ro', 'MarkerFaceColor','r')
grid
That’s an appropriate approach. Adapting the posted code to work correctly with those changes may require some experimentation, because I have no idea if ‘f’ is used elsewhere in the loop. In order to use a specific (scalar) value of it, rather than the entire vector, after these changes, the scalar reference would require that it be used as ‘f(i)’ rather than ‘f’.
