getting error creating coefficient matrix for cramers rule
显示 更早的评论
I am implementing Cramer's Rule into MATLAB and I am stuck on the coefficient matrix part as it gives me an error
% for size of matrix
n=input('');
% co-efficient matrix
coef=zeros([n n]);
and then I get an error stating that I need real integers for the zeros function
Does anyone know how to fix this? Thanks in advance.

Works fine for me, as long as a positive integer is entered, e.g.,
>> % for size of matrix
n=input('');
% co-efficient matrix
coef=zeros([n n]);
5
>> coef
coef =
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0

% co-efficient matrix

Here coef would be an array of size nxn with all elements equal to zero.The dimensions of an array need to be integers (array dimesion can be 0 as well). The error you get is mostly because you're inputting a non-integer value for n.
