Good evening\morning

I wrote a code that will give me a root for a function using Bisection Method and False Position Method

I want to print on output file the follownig

k \t x2 \t absolute_c \t mid\t absolute_m\t

i tried to print it using

result= [i;x2;absolute_m;mid;absolute_m]; fprintf(fid,'%.2f\t\t\t %.6f\t\t %.6f\t\t\t %.6f\t\t %.6f\t\t\n',i,result); but it didn't work

how can I print this?

fid = fopen('hw6.txt','w');  
x0 = input('inter x0 = ');
x1 = input('inter x1 = ');
tolerance=input('inter the tolerance, tolerance =  ');
f = @(x) sin(2*pi*x)+ exp(1.2*x) + x - 2.5;
copy_x0= x0;
copy_x1= x1;
% Using Bisection
for i=0:inf 
      x2= (x0+x1)/2
      c= f(x2)
      absolute_c= abs(c)
      if  absolute_c < tolerance
          break 
      end
      if f(x0)*c <0
          x1=x2;
          continue
      else
          x0=x2;
          continue
      end
      end
  % Using False Position
      for   i=0:inf     
       mid= copy_x1 - (f(copy_x1)* (copy_x1-copy_x0)/(f(copy_x1)-f(copy_x0))) 
              m = f(mid)
              absolute_m= abs(c)
              if  absolute_m < tolerance
                   break 
              end
              if f(copy_x0)*m <0
                            copy_x1=mid;
                    continue
              else
                  copy_x0=mid;
                  continue
              end
      end
      fclose(fid)
