 P: 4 Please I need HELP IMEDIATLY This is the error message that i get ??? Error using ==> gauss_sied Too many input arguments. Error in ==> HW_14 at 23 [x_wo, cnt, x_w,cntt] = gauss_sied(xo, A, b, es, lam); clc clear C = [-8 1 -2 -20 2 -6 -1 -38 -3 -1 7 -34]; A = C(:,1:end-1); b = C(:,end); nr = length(b); xo = ones(1,nr); % initial guess lam = 1.2; n = 4; es = .5*10^(2-n); [x_wo, cnt, x_w,cntt] = gauss_sied(xo, A, b, es, lam); fprintf(' Solution to [A]{x} = {b}\n') fprintf('*******************************************\n') fprintf(' Without Relaxation With Relaxation\n') fprintf(' ******************** ***************\n') for i = 1:length(b) fprintf(' x(i) = %.f x(i) = %.f\n',i,x_wo,i,x_w) end fprintf(' ******************** ***************\n') fprintf(' %i iterations %i iterations\n',cnt,cntt) fprintf('*******************************************\n') Function program function [x_wo, cnt,x_w cntt] = gauss_sied(xo, A, b, lam) %Without Relaxation nr = length(b); ea = 1; cnt = 0; while ea > es for i = 1 : nr sm = 0; for j = 1:nr if i ~= j sm = sm + A(i,j) * xo(j); end end x_wo(i) = (b(i) - sm) / A(i,i); end ea = 100 * abs((x_wo-xo)./x_wo); xo = x_wo; cnt = cnt+1; end %With Relaxation nr = length(b); ea = 1; cntt = 0; while ea > es for i = 1 : nr sm = 0; for j = 1:nr if i ~= j sm = sm + A(i,j) * xo(j); end end x_w(i) = (b(i) - sm) / A(i,i); end ea = 100 * abs((x_w-xo)./x_w); x_w = (lam*x_w) + (1 - lam)*xo; xo = x_w; cntt = cntt+1; end
 PF Gold P: 1,153 You're supplying 5 inputs to a function that is defined to have 4 inputs. function [x_wo, cnt,x_w cntt] = gauss_sied(xo, A, b, lam) called as: [x_wo, cnt, x_w,cntt] = gauss_sied(xo, A, b, es, lam);
 P: 4 Now in my code I get another error Error in ==> gauss_sied at 8 xo = x_wo; Error in ==> HW_14 at 23 [x_wo, cnt, x_w,cntt] = gauss_sied(xo, es, lam, A, b);
