Question

I have two float variables:

x = 0.5;
y = 1.5;

I would like to floor them:

x = floor(x);
y = floor(y);

Can i do it in a single command? this raises an error:

[x y] = floor([x y]);

Answer 1

You can write your own wrapper for floor:

function varargout = myFloor(varargin)
for k = 1:nargin
    varargout{k} = floor(varargin{k});
end

This function shows the required behavior if you provide x and y as two separated arguments

[a, b] = myFloor(x,y)

This results in

a =

     0


b =

     1

If you want to use the concatenated array [x y] as input (like in your example) you can use the following function:

function varargout = myFloor(x)
for k = 1:numel(x)
    varargout{k} = floor(x(k));
end

Then you would call

[a, b] = myFloor([x y])

This results in

a =

     0


b =

     1
