program simulate tossing a coin

Hello everybody please anyone answer me because I want to run this program but some error occurs,How can I solve this problem

N=input('Enter the number of simulations:')

for k=1:N

rand_number=rand;

if random_number<0.5

random_number(k,1)=1;

else

random_number(k,1)=0;

end

end

fprintf('\n')

You assign to rand_number, but on the next line you test random_number

Thank you so much Walter

but I rewrite random_number,when I want to run

this command occur

??? Attempt to execute SCRIPT rand as a function:

C:\Users\N\Documents\MATLAB\rand.m

Error in ==> num1 at 3

random_number=rand;

I think the problem in rand function

but I want to generate random variable and by RAND we can generate random variable

so what is the problem here

[Walter Roberson]

You have accidentally named a file "rand.m", which conflicts with the built-in rand function. You will have to rename C:\Users\N\Documents\MATLAB\rand.m to something else.

Dear Walter,

I changed the name and when I want to running ,there is no any running for program

only this result appear

Enter the number of simulations:33

N =

33

Yup. That's the only thing you request to print out in the code, other than the newline at the end. Your program is now functioning to the limits of all of the requirements you have indicated to us.

The variable name is corrected and the program no longer gives an error, so the matter is solved as far as the initial question is concerned.

You may perhaps now wish to go back and edit the question in order to include an explanation of what you need the program to _do_ and what it does instead, and to include an updated version of your code.

Thank you Walter for your fast response

Now,I solved the question

once again thank you so so much
