Hi, I have set of values for x (x = 1:10) and I have a equation y = x^(1/2)/x, how can i get and display an array of values of y from the x's ?

All i get is one number, when i should be getting a array of y values.

x = 1:10;
y = x.^(1/2)./x
fprintf(' %.2f \n', y)
this is my code

I don't know how you've got one number but I think you should be using:
x = 1:10
y = x.^(1/2)./x

As Star Strider says, thius is the difference between array and matrix operations - i.e. do you want the operation to perform as if your inputs are matrices or not.
If you starts with
A=[2 2 2;2 2 2;2 2 2]
B=[3 3 3;3 3 3;3 3 3]
then A*B will perform a matrix multiplication and give:
A*B
ans =
18 18 18
18 18 18
18 18 18
whereas A.*B will do an array operation and calculate element-wise to give:
A.*B
ans =
6 6 6
6 6 6
6 6 6
Can I also please request that if this answer was of help to you that you accept my answer.
