Hello community,
I am beginner in Matlab. I am struggling with the following exrcises. I only managed to answer 1 & 5 however the others confuse me and I don't even know how to start specially with 2 & 3. Please I need your help
My solutions:
%Exercise 1
x = [2:3:89]
%Exercise 5
function density=ExamC()
x=input('Please enter x: ');
m=input('Please enter mean: ');
s=input('Please enter standard deviation: ');
f=1/(s*sqrt(2*pi))*exp(1)^((1/2)*((x-m)/s)^2);
disp('Value of density is: '), disp(f);
end
Thank you for your help,
Abdel

Or
%Exercise 2:
vec = [1 2 3 4 5 6 7 8 9 10];
vec( 2 : 2 : end ) = 5;

Exercise 1 and 2
"[...] however it confuses me the way the question is written!" Agree; the very same vector has three different names, x, vec and v. (It might be about level of abstraction; an effort to distiguish between the vector and its representation in Matlab.)
Exercise 3.
The text is ok.
Exercise 4.
There are relevant examples in the documentation on plot()
Exercise 5.
The statement
function density=ExamC()
doesn't follow the instruction. The last sentence says
function f = density( x, m , s )
(to my best understanding)
