Hi folks!

I have problems to integrate a scalar function wich is parametrized by 2 Nx1 vectors.

fun = @(b,x,y) (y-exp(-b*x)).'*(y-exp(-b*x));
M = integral(@(b)fun(b,t,z), 0,1);

whereas t and z are previous calculated Nx1 parameter vectors.

Unfortunatly, I get following error message

Error using *
Inner matrix dimensions must agree.
Error in @(b,x,y)(y-exp(-b*x)).'*(y-exp(-b*x))

Error in @(b)fun(b,t,z)

Error in integralCalc/iterateScalarValued (line 314)
                fx = FUN(t);
Error in integralCalc/vadapt (line 133)
            [q,errbnd] = iterateScalarValued(u,tinterval,pathlen);
Error in integralCalc (line 76)
        [q,errbnd] = vadapt(@AtoBInvTransform,interval);
Error in integral (line 89)
Q = integralCalc(fun,a,b,opstruct);

I can't understand the dimension problem since the integrant is scalar function of b.

An help will be appreciated!
