a function that has two inputs: a number and a row vector

The code i am tryin to make requires that there be only two inputs, the first a number and the second as a row vector. How do I do that? I have tried looking online and even in my textbook but i cant find anything.

I should calarify, when calling the function the command window should read My_func(1,[18 11 22 48]).

What I have in my .m file is function y = My_func(a,b,c,d,e), I believe this is where I am having a lack of knowlege.

[Torsten]

function y = My_func(a,bcde)
  b = bcde(1);
  c = bcde(2);
  d = bcde(3);
  e = bcde(4);
end

God bless you.

Answer 1

[Torsten]

scalar = 6.0;
vector = [3 5 8];
output = input(scalar,vector)

function output = input(scalar,vector)
  output = scalar*vector;
end

Answer 2

[KSSV]

function val = myfun(a,b)
 if numel(a) ~= 1 | size(b,1) ~=1
     error('check the inputs') ;
 end
 % Do what you want 
end

[Steven Lord]

Instead of using numel and size here, I recommend using isscalar and isrow or isvector (depending on whether you care about the orientation or just whether or not the input is a vector.)
