Plot the following function over a given interval:
显示 更早的评论
I am new to MATLAB and having difficulty generating a plot over the interval x = [0,7] for following equation:
This is what I have so far:
fplot(exp(0.5*x)*(2*sin(5*x)-0.6*cos(0.7*x)),[0,7])
axis([0,7,-1,1])
Could someone please explain what is wrong with my syntax/formatting? Thank you.

If you haven’t, you have to declare x as a symbolic object.
This works (in R2016b):
syms x
fplot(exp(0.5*x)*(2*sin(5*x)-0.6*cos(0.7*x)),[0,7])

Also this:
fplot(@(x)exp(0.5*x).*(2*sin(5*x)-0.6*cos(0.7*x)),[0,7]) % note the .* after exp(0.5*x)
