a function that has two inputs: a number and a row vector
显示 更早的评论
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.

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

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

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

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.)
