I created a function:

.
x is the excitation wavelength where i will input eg. " test,wavelength(765,y)"
.
y is a 729 by 1 matrix: .

.
the result is:

.
where only the first number of y matrix is being implemented in the function. How do i create a function where the first number of y matrix will be implemented and return as a result as the first number in wavelengtha matrix and so on.

The screenshots are very helpful in understanding your problem. I suggest not using them for the actual code, though, so that we can copy & paste your code into MATLAB ourselves.

1) why you have comma in your function name?
2) Change your equation in element wise division as follow:
wavelengtha= 1./ ((1./x)-(y/10^7))

One way is to do this:
let's say x=[765, 766, 777]
then you can do this:
for i=1:numel(x) wavelengtha{i}= yourFunction(x(i), ...) end
I still don't get the comma in your function name?

I'm not sure I fully understand what you mean, but does this do what you intend?
wavelengtha = 1./((1./x) - (y/10^7));
Notice that I used element-wise division.
