function r = rank(A,tol)
%RANK Matrix rank.
% RANK(A) provides an estimate of the number of linearly
% independent rows or columns of a matrix A.
% RANK(A,tol) is the number of singular values of A
% that are larger than tol.
% RANK(A) uses the default tol = max(size(A)) * eps(norm(A)).
s = svd(A);
if nargin==1
tol = max(size(A)) * eps(max(s));
end
r = sum(s > tol);
>>>Error using rank (line ) Not enough input arguments<<>> s = svd(A); <<<
My matrix is A=[1 4 3 7 ; 2 6 8 3 ; 1 3 4 5 ; 4 13 15 15] And I am trying to calculate rank of A.

How are you calling it?
Are you including a value for ‘tol’ as your function requires?

When I run the det function with it independently, the deteminant is 0.
If you don’t want it displaying in the Command Window, you have to put the semicolon after the call to the function:
y=davaleba(a);
The semicolon after the first line of the function itself does nothing.
