Hey guys. I have a problem with my code below, the problem is: when i run it In the command window there are many calculations and the message to each is something like this: Columns 999279 through 999292, and i don't want to display this over and over again. So please Help

function f=Monar(nr_s)

vect_n=[];

vect_S=[];

ok=0;

for i=1:nr_s

fprintf('scalation factor %d ',i)

S=input(' S=')

fprintf('how many photos with scalation number %d does we have? ',i)

n=input(' n=')

vect_S(i)=S;

vect_n(i)=n;

end

D=[0:0.0001:100];

for i=1:length(D)

f(i)=0;

for j=1:length(vect_S)

f(i)= f(i)+vect_n(j)*(1/vect_S(j))^D(i);

end

f(i)=f(i)-1;

if ok==0 & f(i)-0.00001<0

D(i);

ok=1;

end

plot(D,f);

end

This code stated from this: (I want all the constants(like n1,n2..,s1,s2..) to be entered from the keyboard)

clear all;

clc;

ok=0;

n1=3;

s1=3;

n2=1;

s2=3/2;

n3=0;

s3=1;

D=[0:0.0001:100];

for i=1:length(D)

f(i)=n1*(1/s1)^D(i)+n2*(1/s2)^D(i)+n3*(1/s3)^D(i)-1;

if ok==0 & f(i)-0.00001<0

D(i)

ok=1

end

plot(D,f);

Put a semicolon ; at the end of each line you do not want to print to the Command Window.

See: MATLAB Operators and Special Characters for information on this and others.

that's the point, I couldn't be able to find which line lists those results

It appears to be ‘D(i)’ here:

D=[0:0.0001:100];
for i=1:length(D)
   f(i)=n1*(1/s1)^D(i)+n2*(1/s2)^D(i)+n3*(1/s3)^D(i)-1;
   if ok==0 & f(i)-0.00001<0
       D(i)
       ok=1
   end
end

It only ptinrs as ‘ans’, so I just went through and looked for lines without ending semicolons. When I added a semicolon to that line, ‘ans’ disappeared, although ‘ok’ from the line below it continued to print. That was the only one I found in the code you posted.

The other problem could be that when you call your function, that I assume is:

f = Monar(nr_s)

that you did not put a semicolon at the end of that call. Put a semciolon at the end of that:

f = Monar(nr_s);

and the output ‘f’ should not print.
