Shannon fano coding

[EDIT: 20110526 14:48 CDT - reformat, clarify - WDR]

array = input
iparray=sort9array, 'descend)
len = lenght(iparray)
global M
M = zeros(len,len)
M = M-1
starting_function(iparray)
fprintf(codes in Array format are:/n ') % arranges the array M
   op = [ ]
  if (M(j,,i)==0/M(j,i) represents each array with 1 or 0
     op(i) = M(j,i)
   end;

The code line with j and i is giving me errors

It appears that on the IF statement line, you have a comment that is not preceded by the % symbol.

Hard to say, there are so many typos. Could be the missing apostrophes. Could be the extra comma on that line. Could be the 9 instead of ( .

Hmmm, I thought I had posted asking Christopher to post the actual code: what is shown here does not have any chance of working.

Answer 2

There are several errors in this code.

1. Missing opening parenthesis on line 2.
2. Extra comma on line 2 (or missing first argument).
3. Missing apostrophe in FPRINTF call on line 8.
4. Double commas in IF condition on line 10.
5. Missing % (comment specifier) on line 10.
6. Missing closing parenthesis on line 10.
7. Use of i and j ( both are the imaginary unit) as indexes without defining them first.

Also, M is defined as a zero array, so 0/M(anything) is NaN. Your IF condition will never be met as you have it.

Also, unless you have previously masked the INPUT function, line 1 is not using the INPUT function correctly...

Also, unless you have a custom function called LENGHT, you have misspelled the function LENGTH. (Thanks Walter.)

I am suspecting that the / in line 10 is being used like C++'s // comment indicator...

Anyhow, another issue is that "lenght" has been used instead of "length".
