where is the error ?

function [ vmin ] = mini(vect)
    %MINI retourne le minimum d’un vecteur
    n = numel(vect); 
    if n == 0
        vmin = []; 
    else
        vmin = vect(1);
        for k = 2:n
            if vect(k) < vmin
                vmin = vect(k);
            end
        end
    end
end

function [ vmax ] = maxi(vect)
    %MAXI retourne le maxiimum d’un vecteur
    n = numel(vect);
    if n == 0
        vmax = []; 
    else
        vmax = vect(1);
        for k = 2:n
            if vect(k) > vmax
                vmax = vect(k);
            end
        end
    end
end

what error are you encountering ?

[KHAIF HICHEM]

show this :

??? Input argument "vect" is undefined.

Error in ==> mini at 3

n = numel(vect); if n == 0, vmin = []; else vmin =

[Adam Danz]

If your function breaks the first time it's sole inputs is accessed and the error is that the input variable 'vect' is undefined, that suggests you're running the function without an input.

You aren't just clicking the green Run triangle without passing in vect are you???

[Adam Danz]

That's my bet (what Image Analyst said). If you'd like to run your code with default values for when there are no inputs specified, add this to the top of your code.

if nargin == 0
    vect = [1 2 3 4 5];  %whatever your default values are
    warning('Default values entered in %s.m', mfilename)
end

defining the variable in the base workspace is not enough .you need to go to the command line and

mini(v)

[KHAIF HICHEM]

can you show me ho to do ?

Answer 1

[M]

In the command line, where you defined v, call the function this way:

>> v= [1 2 3 ;4 5 6];

>> mini(v)
