Help with an error

Hello,

I want to ask you how can I solve such an error.

The thing is I want a 2-D array that grows.

x has a length n and is a column vector

L is an nxn vector

this is the prototype of the code.

I cant figure out a way to solve such a question

function [Nt,xe,ye]= PopulationProgress(x,L)

%x=[200000,300000,500,1500]'

i=0;

n=length(x);

Nt=Zeros(n,3);

Nt(:,1)=x;

Nt(:,2)=L*Nt(:,1);

while Nt(:,i)= Nt(:,i+1)

      i=i+1;

      Nt(:,i)=L*Nt(:,i-1);

      Nt(:,i+1)=L*Nt(:,i);

end;

ye=i;

xe=Nt(:,i);

Thank you for any suggestions

Best

Answer 1

MATLAB is case sensitive, replace your

Nt = zeros(n,3) 

i = 1,

MATLAB does not allow indices to be '0';

Answer 2

[Walter Roberson]

In your "while" statement, you need to use "==" rather than "="

Yup, I figured it out. Yet still I am getting an error.

I don't know why.

Nt=Zeros(n,3);

Nt(:,1)=x; have the same size

I am not sure about the syntax of the coding though.

I want the column to be equal to x.

Is this how am I supposed to do it?
