MATLAB: Couldn’t figure out what’s not working

Question

hi, this is the code

executing => THIS IS THE FIRST ITERATION

tab =

     7     8     9    10    11    12    13    14    15    16    17    21    22    25

f1 =

236

m1 =

   12

r1 =

    0

wi =

    0

f =

240

but the real result is

f1 =

   236

m1 =

    11

r1 =

    16

wi =

     1

f =

   232

'f' should be 232 not 240 and it is the same code, where is this 240 coming from??

thank you

Answer 1

the problem is that your f1 is not a double but an integer hence the division also gives an integer

if you cast f1 to be a double you should get the expected result

f1 = double(f1);
m1 = floor(f1/delta)
etcetera
