Hi, I'm a bigginer and what I need is too specific.
I need to plot a graph that looks exaclty like this:
I have a h vector of size 4. a matrix X of size 4x39 and a matrix f(x) of size 4x39.
each line represents the ploting of row i in matrix X with corresponding row i in matrix f(x) for h(i).
Can someone please tell me how to plot this?
Thank you

Something like this
X; % 4x39
f; % 4x39
h; % 4x1
plot(X.', f.')
xlabel('x')
ylabel('(approximate) f(x)')
legend_strs = compose('Approximate f with h=%.2f', h)
legend(legend_strs)
