error - not enough input arguments......in a function

the following function Vheatsource.m is showing error for not enough input arguments ...... after supplying all the relevent input arg... Vheatsource.m

function [ QV ] = Vheatsource( x, y, z, ro, re, ri, H, q, betatwo )

QV=zeros(11*101,101);

    for kk=1:11
        for ii=1:101
            for jj=1:101  
                QV((kk-1)*101+ii,jj)=((9*q*exp(3)*betatwo)/(pi*(exp(3)-1)*H*(re^2+ri^2+re*ri))*exp((-3*((x(jj)^2)+(y(ii)^2)+(z(kk)^2)))/((ro((kk-1)*101+ii,jj))^2)));

            end
        end
    end

where

the input x,y,z is taken from a function heatsourceposiyioning.m which is giving desired result. ro is determined by Rnod.m and running properly. ri, re, H, q have constant values

We need to see the full and original error message copy/pasted, instead of a transcribed summary.
