Hi, im creating a function that calculates the number of partitions of an integer k, but with values like 20 or higher it gives me this error:
File "<stdin>", line 4
SyntaxError: more than 255 argumentsFile "<stdin>",
this is the code, any suggestions? Thanks:
syms x ex Gs
k=input('enter an integer to calculate its partitions : ')
for j=1:k
for i=1:k
if(i*j>k)
break
end
ex(i,j)=(x^j)^i;
endfor
Gs(j)=1+sum(ex(:,j));
endfor
E=expand(prod(Gs));
c = coeffs(E);
Partitions=double(c(k+1))

Your code does not call any function called stdin (which is not a function that comes with matlab in any case).
Moreover, your code is not even valid matlab. endfor does not exist. It's just plain end.
Also note that matlab is not C. The brackets around the for expression and the if test are not needed.
Finally, in your code, x is undefined.

I forgot the first line where i defined x, and I compiled using octave, I know my program doest not call stdin thats why i find it weird, but I will try to run it with matlab to see if the error goes away
