How can I fix this error message: Unable to perform assignment because the left and right sides have a different number of elements?

I try to call a function on my Matlab script, but when I start the simulation, I have this message: 'Unable to perform assignment because the left and right sides have a different number of elements' for the function: 'intersection1sph2' as you see in the code. How can I fix it?

Code:

No1a(1) = 20; Qo1a(1) = 20;

for k = 1:1:1800

% call of intersection's function : a (o1,a) 1s [LEAVEo1al(k),LEAVEo1at(k),LEAVEo1ar(k),No1a(k+1),Qo1a(k+1)] = intersection1sph2(ENTERo1al(k),ENTERo1at(k),ENTERo1ar(k),No1a(k),Qo1a(k),k); LEAVEo1a(k) = LEAVEo1al(k) + LEAVEo1at(k) + LEAVEo1ar(k);

end

We have no information about the sizes returned by the function.

Hi,

As stated by Walter, it is necessary to have a look at your function file: intersection1sph2 without it - it is just a guess to play with k and k+1 index values and assignments.

Good luck.
