MATLAB: How to input a matrix (variable) in a function

functionmatrix

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.

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))

The output variable is whatever you want to call it. You have to call it ‘wavelengtha’ internally in order for the function to return that variable as output, but ‘wavelengtha’ is only local to your ‘test’ function.

You would call the function, for instance with variables ‘x_1’ and ‘y_1’ and you want to call your wavelength ‘lambda_1’, simply call your function with:

lambda_1 = test(x_1,y_1)

MATLAB: How to create a for loop in function with a step size as input

You may be able to avoid the for loop altogether and just pass in a vector of the values from 765 to 805. This should work since your code is already set for element wise operations (due to the presence of the periods). Try the following

 stepSize    = 5;
 x           = 765:stepSize:805;
 y           = 42;
 wavelengths = test(x,y);

We initialize x to be a vector that starts at 765, has a step size of 5, and ends at 805, which is just

 x =
   765   770   775   780   785   790   795   800   805

You should be able to adapt the above for variable step sizes.
