Matlab Defining A Function That Has Vector As An Input

I was given a simple exercise by my professor, which is to define a cerrtain function. Here is my function

function [a,b,c] = PHUN([x,y],[z,t,w])

a = x
b = ((y+z)^2)*t 
c = z/w + x

However, matlab states that I am using invalid syntax in the first line. So, I figured, perhaps there is a particular way in which vector inputs are supposed to be typed. I have attempt several searches on defining functions with vector inputs (or arguments), but have not been successful. I was wondering if someone could possibly help me.

You can pass vectors as arguments in the same way you pass variables. Then access them in the function body appropriately. Your function could be re-written as follows:

function [a,b,c] = PHUN(X,Y)

a = X(1)
b = ((X(2)+Y(1))^2)*Y(2) 
c = Y(1)/Y(3) + X(1)

Or if you want to keep the original variables:

function [a,b,c] = PHUN(X,Y)

Z = num2cell([X,Y]);
[x,y,z,t,w] = Z{:};

a = x
b = ((y+z)^2)*t 
c = z/w + x
