Matrix dimensions must agree.

i dont where the wrong in this equation:

function F = Fint(a)

F = quad(@(x)(x.*sin(x))./(1-(2.*a.*cos(x))+a.^(2)),0,pi);

end

where the output i got is

Matrix dimensions must agree.

Error in Fint>@(x)(x.*sin(x))./(1-(2.*a.*cos(x))+a.^(2)) (line 2)

F = quad(@(x)(x.*sin(x))./(1-(2.*a.*cos(x))+a.^(2)),0,pi);

Is a a vector or scalar ?

[Jefri Nazulrullah bin Zulkepli Amin]

a vector, the question is to Return the F-values in a vector the same size as the a-vector

To integrate a vector, use the quadv (link) function.

If you have R2012a or later, use integral (link) with the 'ArrayValued' option instead.

thanks, its work.

As always, my pleasure.
