Function input vector specifiers

Is there a way to specify all elliments of a vector in a functions input term?
ie. instead of writing
val_1 = mat_val(1,1)
val_2 = mat_val(1,2)
val_3 = mat_val(1,3)
val_4 = mat_val(1,4)
function [ret_val] = filename (val_1, val_2, val_3 , val_4)
ret_val = val_1*val_3 - val_4 + val_2
end
I can have a specifer with the correct syntax to match
function [ret_val] = filename(mat_val(1,:))
ret_val = val_1*val_3 - val_4 + val_2
end
The functions return will be called in a seperate script file.
Thanks

It is always a good idea to use an array instead of separate variable names: https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval. However, the following shows a somewhat acceptable way
function [ret_val] = filename(varargin)
[val_1, val_2, val_3, val_4] = varargin{:};
ret_val = val_1*val_3 - val_4 + val_2;
end
Call it like this
y = filename(1, 2, 3, 4)
