Dear All
In the above example, how can I proceed to perform the product (see function
fct_angles2) ?
Indeed, theta are 2 vectors, so no problem for the fct_angles . but in case
of product, it's naturally not work !!! what is the correct syntax in order
to use vectorization ?
Thanks
Paul

mode(0)
function vect_fct=fct_angles(i, j)
vect_fct = [cos(i)+sin(j) -sin(j) i j];
endfunction
function vect_fct2=fct_angles2(i, j)
vect_fct = [cos(i)*sin(j) -sin(j) i j];
endfunction
B1 = zeros(130321,4);
theta_vect = (0:360)'.*.ones(361,1);
fi_vect = (ones(361,1)'.*.[0:360])';
B1 = fct_angles(theta_vect([1:130321],1),fi_vect([1:130321],1));
B2 = fct_angles2(theta_vect([1:130321],1),fi_vect([1:130321],1));
