About Array Element Division Problem in Loop

[Aziz YÜCELEN]

Hi,

I m newbee and i have a problem about array element division in loop.Can you help me please? Here my code

Get_N_value = input('Enter N value: ');

Get_alpha_count =(2*Get_N_value)-4;

Get_beta_count =(Get_N_value-1);

b_count =(Get_N_value-2);

s_count =b_count;

for gac=1:Get_alpha_count

  sprintf('Enter alpha  %d th value:', gac)

  alpha_value(1,gac) = input('',gac);

end

for gbc=1:Get_beta_count

  sprintf('Enter beta %d th value:', gbc)

  beta_value(1,gbc) = input('',gbc);

end

for i_index=1:b_count

m=(beta_value(i_index)-beta_value(i_index+1))/beta_value(i_index)

end

and result:

Enter N value: 5

ans = Enter alpha  1 th value:

2

ans = Enter alpha  2 th value:

0

ans = Enter alpha  3 th value:

2

ans = Enter alpha  4 th value:

2

ans = Enter alpha  5 th value:

1

ans = Enter alpha  6 th value:

3

ans = Enter beta 1 th value:

2

ans = Enter beta 2 th value:

2

ans = Enter beta 3 th value:

4

ans = Enter beta 4 th value:

4

m = 0

m = -0.040000 <---- this is actually -2/2 = -1 but octave find -0.04000

m = 0
