Simple MATLAB problem that has me stumped


1. The problem statement, all variables and given/known data
Use an array for single digit values of x [1,10] to find values of y for the equation y = (e^3x) / (sqrt (x+1)).


2. Relevant equations



3. The attempt at a solution
So, I tried defining the function as Function [ (e^3x) / (sqrt (x+1))] = y(x) , but that gave me an error message. I then tried to just define x and y first with syms x; and syms y;, and then define y as y = (e^3x) / (sqrt (x+1)).

However, since this is actually not a function, i was not able to arrayfun() to get the answer that I needed. This is my first MATLAB homework and the TA didn't explain anything, he just said to do it.

Any help would be greatly appreciated.

Here this will fix your problem

Code:
x = 1:10;
y= (exp(3*x)) ./ (sqrt (x+1))
Take note of the dot (" . ") That tells matlab to perform a value by value operation rather than a matrix operation.
