I don't get the correct output from my function
1 view (last 30 days)
Hello community. I've struggled for a bit now with this.
I don't understand how I can get elementwise multiplication and addition to work here. The graph is not what it should look like when I run this program. I've tested with other software, such as Geogebra. Other than that, when I change the range from -5 to -10, the graph shifts with it.
I just don't see how to fix this problem. I would love help on this. Thanks.
values = -5:0.1:5;
f = @(x)(exp(1-2.*x).*(x+cos(2.*x)));

The function is correct. However, because this function outputs very large numbers depending on your range (in terms of absolute value), you end up with missing the details that you appear to be looking for.
Try the following:
f = @(x) exp(1-2*x).*(x+cos(2*x))
