How do I input a matrix (variable) in a function?

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?

sorry i have rename my function to just
.
function [wavelengtha] = test(x,y)
wavelengtha = 1./ ((1./x)-(y/10^7));
for i=1:numel(x)
wavelengtha{i}= test(x(i), ...);
end
end
. However i cant get the for loop to work.

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.

Thank you for you help!
As far as i understand. the result will return as a new variable in my workspace. Even when i change the input of x. The resulted variable will replace my previous work. is there a way to have the resulting variable number somewhat related to my input x eg(x = 765. then the wavelengtha out automatically output as wavelengtha765 something like that)
