[Users-fr] applying function to a matrix

[Vincent Douce Mathoscope]

hi
i am not very ease with scilab but i have to help some stundents of mine on that topic
i thought that applying any function on a matrix would apply affect every item of that matrix
example sqrt(A) would that the sqrt of each aij of A
in this logic i wanted to simulate a binomial law by creating this bernoulli function :

function xp=f(x, p)
    if x<p 
        then xp=1
        else xp=0 
    end
endfunction

and apply it to a grand of ramdom x in [0,1] like that :

function bn=binomiale(n, p)
    a=grand(1,n,"unf",0,1)
    ap=f(a,p)
    disp(ap)
    bn=sum(ap)
endfunction

but it doesn't work

it seems like scilab would try to apply f to a as an object itself

could aynone help me understanding ?

thanks
