Window not accommodate my formulated analytical equations (Qy), it might go thousands, probably due to coded through sprintf; any assistance please

my code need alot of data to nonlinear equation,

function [FUN] = magige222(matr)                                      
        matL=abs(matr);   [NodLp,pQ]=size(matr); data1=3; data2=data1+2-1; Nod3=NodLp-data1;   p=pQ-1; nodes=9; LP=Nod3-nodes; JJ=NodLp-8+1;    HLD=0;             % matr loop eqns; not general matrix (MAG)
 FUN = 'FUN=@(Qy)[';
      for j=JJ:NodLp                              % looping headloses eqns
              for k=1:p     
                     if (sum(matL(j,1:k))<=sum(matL(j,1:p)))&&matL(j,k)~=0 FUN = [FUN, sprintf('(%d.*Qy(%d).*abs(Qy(%d)*8.*L(1,%d)*1./(9.81*3.14.^2.*D(1,%d).^5).*(0.25.*(log10(ee./(3.7.*D(1,%d))+2.51*3.14*vs.*D(1,%d)./(4.*Qy(%d)).*(0.25.*(log10(ee./(3.7.*D(1,%d))+2.51*3.14*vs.*D(1,%d)./(4.*Qy(%d)).*(0.25.*(log10(ee./(3.7.*D(1,%d))+2.51*3.14*vs.*D(1,%d)./(4.*Qy(%d)).*0.00001.^-0.5)).^-2).^-0.5)).^-2).^-0.5)).^-2)))+',matr(j,k),k,k,k,k,k,k,k,k,k,k,k,k,k)]; end
                     if (k==p)                                             FUN = [FUN, sprintf('(%d);',matr(j,k+1))]; end 
              end
       end  
       for j=data2:NodLp-8                        % Nodal mass balance eqns
              for k=1:p     
                     if (sum(matL(j,1:k))<=sum(matL(j,1:p)))&&(matL(j,k)~=0) FUN = [FUN, sprintf('(%d.*Qy(%d))+',matr(j,k),k)]; end
                     if (k==p)                                               FUN = [FUN, sprintf('(%d);',matr(j,k+1))]; end                                         % FUN = [FUN, sprintf('matr(j,k+1);',j,k)]; end    
              end
       end 
   
       FUN = [FUN, '(1.*Qy(1))+(-1.*Qy(2))+(0);(1.*Qy(2))+(-1.*Qy(3))+(-1.*Qy(9))+(-1.*Qy(15))+(-5.900000e-02);(1.*Qy(3))+(-1.*Qy(4))+(-1.*Qy(8))+(-5.900000e-02);(1.*Qy(4))+(1.*Qy(5))+(-1.*Qy(7))+(-1.780000e-01);(-1.*Qy(5))+(1.*Qy(6))+(-1.*Qy(11))+(-1.*Qy(12))+(-5.900000e-02);(1.*Qy(7))+(-1.*Qy(10))+(1.*Qy(11))+(-1.*Qy(13))+(-1.900000e-01);(1.*Qy(8))+(1.*Qy(9))+(1.*Qy(10))+(-1.*Qy(14))+(-1.780000e-01);(1.*Qy(14))+(1.*Qy(20))+(1.*Qy(21))+(-9.100000e-02);(1.*Qy(16))+(1.*Qy(19))+(-1.*Qy(20))+(0);(1.*Qy(15))+(-1.*Qy(16))+(1.*Qy(17))+(0);(1.*Qy(17))+(-1.*Qy(18))+(-3.000000e-02);(1.*Qy(18))+(-1.*Qy(19))+(-3.000000e-02);(1.*Qy(12))+(1.*Qy(13))+(-1.*Qy(21))+(0)];'];

the output those I got as executed the code

expected output is

as well assisted by Walter in few day ago

Thanks

I don't understand your question and I don't understand why on earth you are creating a char vector of a function. What is your end goal?

Also, you didn't @-mention Walter, so he may not notice this new question.

Hi Rik as well as Walter,

Actually Walter assist me alot. The code and the formulate the nonlinear analytical model (sometime has hundereds to thousands eqns). The model is OK, particularly for few datasets (<50); and initially I had used fprintf, but Walter recommened to use sprintf as to mitigate the challenges of fsolve and manipulation of FUN, @, etc;Walter, might aiming model simplification etc. Furthermore, we still have chance to use fprintf as to allow many rows than just one (which had trucanted (warned) by matlab, see the matlab output). Would you assist me, please

[Rik]

What are you trying to do?

Also, @Walter Roberson might have helped you before, but might not be aware of this thread.

[Eng. FM]

Walter you have being assist me and our other collegues. Thank you for your tireless effort

Yes, my model stop to execute other assigned task; I think the space in window not enough as I got the following warn .. (could see above)

Output truncated. Text exceeds maximum line length

Yet, we still need your assistance
