Unable to perform assignment because the left and right sides have a different number of elements.

im trying to create a matrix from the output of each iteration (h1) where h1 changes each time but keep getting this error message

'Unable to perform assignment because the left and right sides have a different number of elements.'

This is my code

%Get time delay and no. of turbines from user

user=input('Enter a delay time from 1 to 20944: ');

N=input('Enter a number of turbines: ');

%initial h1

h1=14.05;

%ch1=change in h1

%nh1=new h1

for i=1:(20944-user)

h2=TideHeight(user+656+i,1);

Q=Cd*N*(pi*(d/2)^2)*(sqrt(2*g*(h1-h2)));

ch1=Q/A1;

nh1=(h1-ch1);

h1(i)=nh1

end

Hi,

While calculating Q you are using h1 rather than an element in h1 vector . Hence size of ch1and consequently nh1 which are dependent on Q is not 1x1 as i increases. Thus the assignment h1(i)=nh1 throws error as the size of h1(i) is 1x1 where as the size of nh1 is not 1x1
